Emerging Photocatalysts for Hydrogen Evolution

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.
