Facile synthesis of Zn0.5Cd0.5S nanosheets with tunable S vacancies for highly efficient photocatalytic hydrogen evolution

Porous Zn 0.5 Cd 0.5 S nanosheets with a controlled amount of S vacancies were prepared by a multistep chemical transformation strategy. The photocatalytic activity of Zn 0.5 Cd 0.5 S nanosheets prepared by 4 h hydrolysis is 20.5 times higher than that of Zn 0.5 Cd 0.5 S(en) x intermediates.
