Photocatalytic hydrogen (H2) evolution has been regarded as one of the most promising approach to convert solar energy into chemical energy. Semiconductor materials have been shown a significant interest in photocatalytic H2 evolution reactions. Recently, CdS (Eg=2.4 eV) was reported to show sufficient visible-light photocatalytic hydrogen generation. It is well-known that many properties of CdS such as morphology, size, and specific surface area can affect its photocatalytic activity. Thus, controlling the shape and size of CdS is a crucial factor in a highly active photocatalyst. Here, we are proposed to synthesize the different sized CdS nanorods at different temperatures/reaction times. The performances of synthesized nanorods are evaluated by H2 evolution reaction under visible light irradiation. |
