Abstract

ZnS:Ag₂S porous nanostructures are prepared by a simple ion-exchange route using ZnS nanosheets as sacrificial templates. In solutions of different Ag ion concentrations, ZnS nanosheets are partially converted to Ag₂S, resulting in porous ZnS:Ag₂S nanosheet composites with different pore sizes. With the Ag₂S nanocrystals playing the role of hole scavengers, the porous nanosheets exhibit a high photocatalytic H₂ generation rate of 104.9 μmol/h/g without using any noble metal cocatalyst. © 2014 American Chemical Society.
