报告内容简介：

What is carbon neutrality? Carbon neutrality means net zero carbon. This means that any actions that lead to emissions would be accompanied by other actions that confidently reduce or offset the emissions. I think that new developments in carbon neutrality lie in a broad range of low-carbon technologies including renewable energy and energy storage, decarbonization of traditional energy, carbon capture, carbon sink and carbon sequestration, strategies to tackling climate change as well as environment and energy.

The massive consumption of fossil fuels has induced global warming due to an increase in atmospheric CO2 concentration as well as environmental and energy issues. A promising scientific approach to address these issues is to develop clean and sustainable energy which also enables to reduction of CO2 emission. Converting clean and unlimited solar energy into H2 through photocatalytic overall water splitting is an ideal and key technology for the production of environmental, sustainable, and ecological clean energy to achieve a carbon-neutral society. As shown in Fig. 1, in the 19th and 20th centuries, catalysis played an important role in overcoming difficult problems threatening human survival. In the near future in the 21st century, photocatalysis to produce H2 from water under sunlight light irradiation (Solar Hydrogen) will play a decisive role in Caron Neutral society in the same way as catalysis did.

报告内容简介：

Dye-sensitization of a wide-gap oxide is a typical example of artificial photosynthetic scheme for water splitting. While dye-sensitized metal oxides are good candidates as H2 evolution photocatalysts for solar-driven Z-scheme water splitting, their solar-to-hydrogen (STH) energy conversion efficiencies remains low because of uncontrolled charge recombination reactions. Here it is shown that modification of Ru dye-sensitized, Pt- intercalated HCa2Nb3O10 nanosheets (Ru/Pt/HCa2Nb3O10) with both amorphous Al2O3 and poly(styrenesulfonate) (PSS) improves the STH efficiency of Z-scheme overall water splitting by a factor of ~100, when the nanosheets are used in combination with a WO3-based O2 evolution photocatalyst and an I3–/I– redox mediator, relative to an analogous system that uses unmodified Ru/Pt/HCa2Nb3O10. The Al2O3 and PSS modifiers, which have previously been shown to suppress back electron transfer reactions in a dye-sensitized H2 evolution photocatalyst, enabled operation of the Z-scheme system even at low intensity of simulated sunlight without a decrease in the STH values. By using the optimized photocatalyst, PSS/Ru/Al2O3/Pt/HCa2Nb3O10, a maximum STH of 0.12% and an apparent quantum yield of 4.1% at 420 nm were obtained, by far the highest among dye-sensitized water splitting systems and also comparable to conventional semiconductor-based suspended particulate photocatalyst systems.

报告内容简介：

Graphitic carbon nitrides are widely studied in photocatalysis. When mixed with electron donors and excited with light, carbon nitrides undergo photocharging – they form persistent radicals, which survive for days under anaerobic conditions. These persistent radicals are sufficiently reactive to serve as reductants in the dark. Therefore, the whole photochemical process can be separated into two steps – i) light harvesting and energy storage in the form of reactive radical species in the semiconductor and ii) chemical reaction in the dark using stored in the carbon nitride electrons. The density of electrons stored in the photocharged carbon nitride defines reductive power of this state. A mildly-photocharged carbon nitride, in which statistically one electron is stored on a large number of heptazine units (typically > 20), is a stronger reductant compared to a carbon nitride, in which statistically each heptazine unit bears an extra electron. These unexpected findings allow using carbon nitrides and solar light to enable uphill reactions and potentially contribute to carbon neutrality.

报告内容简介：

Highly selective converting CO/CO₂ to target fuels and chemicals attracts wide attention, due to its high efficiency, controllable product selectivity, and industrial application prospect. In recent years, our group developed some new synthesis reactions by tailor-made catalysts in CO/CO₂ hydrogenation, realizing the efficient production of liquid fuels and various chemicals, such as ethanol, gasoline (C₅-C₁₁), jet fuel (C₈-C₁₆), diesel (C₁₀-C₂₀), value-added aromatics, and so on.

Aromatics, as the most important platform chemicals in the polymer industry, are mainly produced from the petroleum refining process. It is highly urgent to seek an alternative pathway for aromatics synthesis, especially para-Xylene (PX). As shown in Figure below, a newly designed bifunctional catalysts composed of reducible metal oxide and modified acidic zeolite (H-ZSM-5@SiO₂) were developed for the direct synthesis of aromatics from CO/CO₂ hydrogenation. After regulating the external surface acidity of zeolite, the production of PX was obviously promoted, achieving the high PX selectivities of 27.6% and 38.7% in CO and CO₂ hydrogenation, respectively. Recently, our research group is cooperating with Nippon Steel Corporation to explore the key industrial issues for the large-scale production of PX from CO/CO₂ hydrogenation (funded by NEDO).

Direct production of liquid fuels from CO/CO₂ hydrogenation is also an important research direction. We loaded cobalt nanoparticles on alkaline ions (La, Ce and K) modified mesoporous Y-zeolite for CO hydrogenation. By tuning the porosity and acid properties of zeolite, different kinds of liquid fuels were produced. Outstanding selectivity of gasoline (74%), jet fuel (72%) and diesel fuel (58%) were respectively achieved in CO hydrogenation via Fischer–Tropsch synthesis.

In addition, a self-catalytic reactor (SCR) prepared by metal 3D printed technology, was first designed and applied for CO/CO₂ hydrogenation reactions by our group. The hydrocarbons distribution in CO hydrogenation could be regulated by simply tuning the inner geometrical structure of Co-SCR. Without any additional catalyst, the brand-new SCR perfectly integrates the metal-based catalyst and reactor. This technology develops a new research direction for C1 catalysis and makes on-board, on-ship, or on-ocean compact chemical factory realizable.

In conclusion, these new synthesis reactions driven by tailor-made catalysts have shown great potential of CO/CO₂ hydrogenation technology in providing alternative strategies for fuels and chemicals synthesis. Tremendous progress has been made in the rational design of highly efficient catalysts and novel reaction pathways to realize this promising technology.

报告内容简介：

We disclose a general electrocatalytic hydrofunctionalization by utilizing a wide range of alkenes. The integration of the two involves an electrochemically instigated cobalt-hydride-catalyzed radical-polar crossover of alkenes that enable the generation of key cationic intermediates, which could readily be entrapped by challenging nucleophiles. We highlight the importance of precise control of the reaction potential by electrochemistry in conjunction with the decisive role of 1,1,1,3,3,3-hexafluoro-2-propanol (HFIP) as the co-solvent to obtain optimal and exclusive chemoselectivity.

In addition, we develop an electrocatalytic method for intramolecular hydroamination of allylic sulfonamides to access azetidines. The merger of cobalt catalysis and electricity enables regioselective generation of key carbocationic intermediates, which could directly undergo intramolecular C-N bond formation. The mechanistic investigations including electrochemical kinetic analysis suggest that the catalyst regeneration by nucleophilic cyclization is involved in the rate-determining step (RDS) of our electrochemical protocol and highlight the ability of electrochemistry in providing ideal means to mediate catalyst oxidation.

报告内容简介：

Production of green hydrogen via high-efficiency water splitting by using sustainable energy sources is one of the main strategies toward carbon neutrality. Several new types of hydrogen production strategies, such as piezo-catalytic and pyro-catalytic water splitting, have emerged in recent years, where the spontaneous polarizations of ferroelectric materials have been utilized for hydrogen generation by harvesting mechanical vibration or thermal energies from the surrounding environment. In this talk, I will introduce on our recent work in piezo- and pyro-catalytic hydrogen production with a focus on (1) our proposed band theory of spontaneous polarization driven water splitting, and (2) the strategy to efficiently accelerate the pyro-catalytic water splitting. Finally, a future perspective will be given on the spontaneous polarization driven piezo- and pyro-catalytic reactions including, but not limited to the deeper understanding of the catalytic mechanism, rational design of the nanostructured ferroelectric materials, and potential applications.

报告内容简介：

Energy storage plays a pivotal role across a wide range of applications, including portable electronics, electric vehicles, and renewable energy integration. Presently, lithium-ion batteries (LIBs) are extensively used for various applications due to their unique features. However, concerns have arisen regarding their feasibility and long-term sustainability, owing to the scarcity and uneven geographical distribution of lithium resources. Amidst these considerations, potassium-ion batteries (PIBs) have attracted substantial interest due to their cost-effectiveness and widespread availability. Nonetheless, the significant ionic radius of potassium ions (1.38 Å) presents challenges within graphite electrodes, resulting in electrode materials that demonstrate diminished capacity and limited cyclic stability in PIBs. Among the various reported anode materials for PIBs, phosphorus-based electrodes stand out with the most remarkable theoretical specific capacity (2596 mA h g⁻¹). Unfortunately, these electrodes experiencenotable volume expansion during operation, leading to reduced capacity and insufficient cycling stability.

In this presentation, I will demonstrate that phosphorus-based electrodes in PIBs hold the potential to emerge as competitive alternatives to LIBs for large-scale, sustainable, eco-friendly, and secure energy storage systems. Strategies to enhance the capacity of phosphorus-based electrodes, improve cycling stability, and enhance the electrolyte safety of PIBs will be explored. Of paramount significance, X-ray photoelectron spectroscopy (XPS) has been utilized to reveal essential insights into the dynamic evolution of solid electrolyte interphases on phosphorus-based anodes in organic phosphate-based electrolytes. This approach provides an explanation for the extended cycling stability observed in these systems. Lastly, approaches to enhance the cathode electrode for PIBs will also be discussed.

报告内容简介：

Our aim is to understand processes that lead to the emergence of catalytic function though direct observation using a combination of operando scanning and transmission electron microscopy. Starting with simple model catalysts, such as polycrystalline metal foils, we observe the propagation of chemical waves and reveal how catalytic activity depends on grain orientation, coupling mechanisms and reaction conditions [1]. In the case of redox-reactions on non-noble metals, we find that the active catalyst is operating near a phase-boundary where metallic and oxidized phases co-exist [2]. Real-time imaging reveals fascinating oscillatory redox dynamics that increase in complexity with increasing chemical potential of the gas-phase. When moving from simple model catalysts to industrially relevant metal nanoparticles supported on reducible oxide carriers, we apply in-situ transmission electron microscopy to study effects related to a strong metal-support interaction (SMSI) under reactive conditions [3,4]. Using the archetypical titania supported platinum nanoparticles as a reference system, and hydrogen oxidation as model redox reaction, it will be shown that the well-described encapsulated state of platinum particles is lost as soon as the system is exposed to a redox-active environment. Structural incoherence at the platinum-titania interface lowers the barrier for redox processes, which give rise to dynamic reconstructions and particle migration. The particle orientation on the support determines the structure of the interface and the resulting particle dynamics, migration, and sintering behavior. The aim of the presentation is to demonstrate that active catalysts are dynamically adapting to the reaction environment and that catalytic function is related to the catalysts ability to participate in the reaction through reversible changes in its structure and/or (local) composition.

报告内容简介：

Photocatalytic hydrogen production from water is a research area of immense interest as hydrogen has been identified as a potential energy carrier of the future. Most of the studied photocatalysts are inorganic and organic materials have been far less studied. Here, I will present our work on the application of conjugated materials as photocatalysts for sacrificial hydrogen production from water. [1,2] We have used a range of different techniques that helped us to gain understanding of the properties that are important for the materials performance, including transient absorption spectroscopy. [3-5] Sacrificial water oxidation [6] and non-sacrificial overall water splitting [7,8] were also studied which shows the potential of these materials for the future clean energy generation.

In this presentation, I will in particular focus on solution processible polymer photocatalysts. The use of solution processability offers significant opportunities going forward in scale up, which will be important given future energy needs. I will show that these remain highly active as thin-films and I will present strategies to increase their hydrogen evolution rates further. [4,5,8]
