摘要：
The emerging electrocatalytic refinery (E-refinery) promisingly leads to defossilization, decarbonization, and decentralization of chemical industry. Specifically, powered by renewable electricity (e.g., solar, wind and hydro power), oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) can efficiently split water into green hydrogen. A crucial step in realizing this prospect is the knowledge-guided design of optimal electrocatalysts with high activity and selectivity. In this presentation, I will talk about our recent progress in mechanism understanding and material innovation for electrocatalytic seawater splitting for green hydrogen production.
Aqueous zinc-based batteries (AZBs) and metal-sulphur batteries (MSBs) hold significant potential for energy storage due to their low cost, high safety, impressive energy density, and environmental friendliness. However, they face major challenges for commercialization, including the lack of advanced cathode materials for AZBs and slow reaction kinetics for MSBs. For AZBs, I will introduce our latest advancements that demonstrate the exceptional durability of Zn-I2 batteries in industrial-scale pouch cells, which are operated under conditions of high active mass loading for cathodes and limited Zn supply for anodes. I will show our new efforts to harness the reversible four-electron I−/I2/I+ conversion electrochemistry, aiming to enhance the energy density of Zn-I2 batteries. For MSBs, I will introduce our recent research progress on developing fundamental designing principal of nanocomposite catalysts capable of enabling high-power performance in Li||S battery systems.
