A simple template-free synthesis of nanoporous ZnS–In2S3–Ag2S solid solutions for highly efficient photocatalytic H2 evolution under visible light

Nanoporous ZnS-In(2)S(3)-Ag(2)S solid solutions synthesized by a facile template-free method showed relatively high activities for photocatalytic H(2) evolution under visible-light irradiation (lambda >400 nm) even in the absence of co-catalysts.
