英文摘要	A promising and highly efficient 0.5%Pt/N-Bi2MoO6 photocatalyst was synthesized by two-step hydrothermal route and NaBH4 reduction method to obtain outstanding adsorption performance and photocatalytic efficiency. The degradation yield obtained by 0.5%Pt/N-Bi2MoO6 composite catalyst for orange II was 90.13%, which was 4 times and 1.8 times higher than that of pure Bi2MoO6 and N-Bi2MoO6, respectively. Such prominent photodegradation efficiency was primarily ascribed to the introduction of Pt and N narrowed the band gap of the bulk Bi2MoO6 material and surface plasmon resonance (SPR) effect triggered by Pt nanoparticles (NPs), which significantly broadened the optical absorption range and improved separation efficiency of electron-hole pairs. Furthermore, the effects of the initial pH of the solution, the initial concentration of the catalyst, the optical properties and the loading of Pt were discussed. Notably, the adsorption process could be described by the Freundlich model, where 1/n = 0.536, indicating that the concentration had a weak influence on the adsorption capacity. Finally, it had been determined that superoxide anion radicals (.O-2(-)) and photogenerated holes (h(+)) were the main active species for the degradation of orange II. (C) 2021 Elsevier B.V.
