【 摘 要 】

Auto-combustion method was employed to synthesize one-dimensional (1D) Zn1-xNixO (x = 0, 0.5, 0.1, 0.2, 0.3 and 0.5) nanoparticles for photocatalytic activity. XRD confirmed crystalline structure of pure and Ni-ZnO samples. Morphological and surface information of the synthesized particles was investigated by SEM. DRS results depicted that nanoparticles have direct band gap, which was reduced with Ni doping. The photoluminescence study showed that intensity was decreased with Ni concentration due to reduction of electron-hole pair rate. The influence of nickel concentration as dopant on photocatalytic behavior of Ni-ZnO was investigated. The maximum photocatalytic activity was exhibited by Ni-ZnO (x=5%) as compared to other samples.
