摘要
Photocatalytic H2 evolution from water is a promising avenue for the sustainable production of clean fuels without byproduct pollutants as in the traditional use of fossil fuels. Three water-splitting routes (i.e., POWS, PPWS, and PIWS) have been developed for photocatalytic H2 evolution that involve light-absorption, charge-transport, and surface-reaction processes. A range of cost-effective photocatalysts and cocatalysts have been developed for higher-efficiency H2 evolution. Steady progress on efficiency, scalability, and operability has been achieved towards large-scale H2 production. Hydrogen evolution via solar-driven photocatalytic water splitting (PWS) is considered an important strategy for facilitating clean global energy and overcoming the severe environmental challenges facing our society. As a result, many photocatalysts have been developed over the past several years. In this review, we outline the most recent advances in hydrogen evolution photocatalysts over the past 2 years. In particular, we introduce hydrogen production methods, main and cocatalysts for hydrogen evolution through water splitting, the underlying photocatalytic mechanisms, and current challenges and future potential advances for this exciting field.
