A simple template-free synthesis of nanoporous ZnS-In2S3-Ag2S solid solutions for highly efficient photocatalytic H-2 evolution under visible light

Nanoporous ZnS-In2S3-Ag2S 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.
