Abstract

Noble metal/semiconductor hybrids are potential photocatalysts due to their unique properties. Herein, Pt nanoparticles (NPs) were deposited on Ni_0.17Zn_0.83O support via chemical reduction (using two different reducing agents, NaBH₄ and ascorbic acid (AA)) and photo-deposition. The result analysis proved that the valences state (metallic Pt⁰, Pt²⁺ and Pt⁴⁺) and particle size of Pt were closely related to the reduction treatments. The photocatalytic properties of all samples were evaluated by degradation of Methyl orange (MO), and the photo-deposited Pt/Ni_0.17Zn_0.83O showed the best performance that the degradation rate reached 95% in 1.5 h and remained at 89% after 5 cycles. This study will give a deeper insight for the impact of reduction treatments and provides a new idea for future research.
