Introduction Click to copy section linkSection link copied! Photocatalytic water splitting using semiconductor metal oxides offers a promising approach to converting solar energy into green hydrogen. (1−3) Despite extensive efforts, achieving high catalytic activity remains a major scientific challenge. This limitation arises primarily from fast photogenerated charge carrier recombination and slow surface reaction kinetics.

Electro-oxidation of alcohols over electrochemically activated nickel alloys for energy-saving hydrogen production† Water electrolysis has been considered as a green and sustainable technique for hydrogen production, while the sluggish kinetics of the oxygen evolution reaction (OER) and the insufficient active sites remain bottlenecks for practical performance.

Abstract Electrochemical carbon dioxide reduction is a potential pathway for sustainable production of fuels and chemicals. However, the detailed catalytic mechanism in cells using high-current gas diffusion electrodes remains uncertain.
