Recent advances of hydrogen production through particulate semiconductor photocatalytic overall water splitting

Solar energy-driven photocatalytic water splitting has been investigated for decades to produce clean and renewable green hydrogen.In this paper,the cutting-edge research within the overall water splitting system is summarized from the one-step photocatalytic overall water splitting(POWS)system to the two-step system and the cocatalysts research in this field.In addition,the photocatalytic reaction engineering study is also reviewed which is crucial for future scale-up.This mini-review provides a picture of survey of recent progress of relevant overall water splitting system,with particular attention paid to material system and mechanistic breakthroughs,and highlights the challenge and opportunity of the current system.
