Abstract

The Ni-doped (CuIn) 0.2Zn 1.6S 2 photocatalysts were prepared via a two-step ultrasonic-hydrothermal method under an environmental-friendly condition. XRD pattern profiles suggested that Ni 2+ successfully doped into (CuIn) 0.2Zn 1.6S 2 lattice. UV-Vis spectra indicated that the optical properties of the photocatalysts greatly depended on the amount of Ni doped. SEM images show that the samples were microspheres. The microsphere structures were gradually damaged with the increment of Ni doping amount. The photoactivity of (CuIn) 0.2Zn 1.6S 2 was enhanced when Ni 2+ was doped into the crystal structure. The H 2 evolution performance over the prepared samples from inorganic/organic sacrificial solution was systematic investigated.
