A series of Pd/Cd0.8Zn0.2S/SiO2 photocatalysts were prepared by incipient wet impregnation. The catalysts were characterized by XRD, H2-TPR, XPS, and UV-vis DRS and used in the photocatalytic evolution of H2 from glycerol and water mixture; the effects of Pd loading on the surface structure, photo absorption and H2 evolution rate were investigated. The results showed that the chemical interaction between ZnS and CdS results in the formation of Cd0.8Zn0.2S solid solution on the surface of SiO2; after the modification with Pd, the light absorption region of Cd0.8Zn0.2S/SiO2 is expanded and the photo absorption efficiency is enhanced obviously. The loading of Pd exhibits significant influence on the rate of photocatalytic H2 evolution; over 0.5%Pd/Cd0.8Zn0.2S/SiO2 with a Pd loading of 0.5%, the maximum hydrogen production rates under UV light irradiation and under solar-simulated light irradiation reach 831 μmol·h-1 and 153 μmol·h-1, respectively, which are almost 4 times and 2 times higher than those obtained over unmodified Cd0.8Zn0.2S/SiO2 under UV and solar-simulated light irradiation, respectively. The superior photocatalytic performance of Pd/Cd0.8Zn0.2S/SiO2 can be partly related with the improvement of photo absorption, the enhancement in chemisorption and activation of H2O and the increase in separation efficiency of photo induced electron-hole arising from the Pd modification.
