Photocatalytic Hydrogen Production from Water Splitting on CdS and Cd_0.8Zn_0.2S Nanorods: Influence of Ni(OH)₂ Modification

Abstract:

The composite photocatalysts of Ni (OH)₂ modified Cd_1-xZn_xS (x=0, 0.2) nanorods were synthesized via a simple deposition-precipitation method using nanorods as support and Ni (NO₃)₂ as nickel hydroxide precursor. The structures, morphologies and optical properties of the catalysts were characterized by X-ray diffraction, scanning electron microscopy, high resolution transmission electron spectroscopy and UV-visible absorption spectroscopy. The photoactivities of the catalysts were examined toward hydrogen production by water splitting under simulated solar irradiation. Results show that the catalyst of Ni (OH)₂-Cd_0.8Zn_0.2S nanorods exhibits a significantly enhanced H₂-production activity in compared to the Ni (OH)₂-CdS nanorods. The reason for the different effects of Ni (OH)₂ modification on the photoactivities of the two catalysts was discussed, and the possible mechanism related to the photocatalytic process was proposed.
