报告摘要：Electro-catalysis plays key roles in electrochemical energy conversion technologies such as fuel cells and seawater electrolysis for green hydrogen production. Advanced liquid fuel cells such as direct alcohol (methanol, ethanol, etc.) fuel cells have been regarded as a promising alternative for the power supply for portable and automotive applications thanks to their simplicity of using directly liquid fuels in the feed. The fundamental key challenge in the advanced direct fuel cell and seawater electrolysis is to rationally design efficient, stable and low-cost catalyst and electrode materials. An insight into the structure-reactivity and structure-selectivity relationships is the prerequisite to the effective design of the desirable high-performance electrocatalysts. In this talk, recent progress on the development of low-cost electrocatalysts for both advanced direct liquid fuel cells and seawater electrolysis for green hydrogen production will be reported. Fundamental studies have been performed, employing combined electrochemical in-situ FTIR spectroscopy and density functional theory atomistic modeling, to understand the reaction mechanism and structure-reactivity relationships of a series of low-cost model and practical nano-catalysts, unsupported and supported on various substrates such as oxides and carbides. The effects of supports and electrode structures on catalyst layers towards liquid fuel oxidation and seawater splitting reactions (hydrogen evolution reaction and oxygen evolution reaction) have been demonstrated, and mechanisms understood.
