[Abstract]
Driven by the growing need for clean and sustainable energy sources, a number of carbon-neutral energy conversion technologies have been extensively explored over recent years, which include photo- and electrocatalytic water-splitting systems, fuel cells, and metal ion batteries. In particular, water electrolysis, consisting of hydrogen evolution reaction (HER) and oxygen evolution reaction (OER), is considered a promising and efficient way to produce a clean energy carrier, hydrogen, to meet such energy demands. Green hydrogen produced by renewable-energy-powered water electrolysis could help resolve the energy crisis and cut our carbon footprint at the same time.
So far, the most efficient catalysts developed for both HER and OER make use of precious metals, which largely hinders their wide application due to their high cost and limited availability. Transition metal compounds based on earth-abundant elements can offer an economically viable platform for electrocatalytic chemical and energy conversions. In terms of catalytic efficiency and stability, however, these catalysts still need proper tuning of surface property, electronic configuration, and morphology to win over the noble-metal-based ones. In this talk, several strategies and material systems we develop to realize effective water-splitting catalysis will be presented with a special focus made to the cases of emerging material systems and their characterization.
