Zn(x)Cd(1-x)S photocatalysts have been widely investigated due to their diverse morphologies, suitable band gaps/band edge positions, and high electronic mobility. However, the sluggish charge separation and severe charge recombination impede the application of Zn(x)Cd(1-x)S for hydrogen evolution reaction (HER). Herein, doping of phosphorus (P) atoms into Zn(0.3)Cd(0.7)S has been implemented to elevate S vacancies concentration as well as tune its Fermi level to be located near the …
