摘要
Abstract
A new composite catalyst AgBr/CaMoO4 was successfully fabricated by loading AgBr nanoparticles on CaMoO4 support via a convenient precipitation-deposition method.The microstructure , chemical composition and morphologies of the AgBr/CaMoO4 were characterized by X-ray diffraction ( XRD) , Fourier transform infrared ( FT-IR), X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM).A series of comparative experimental results showed that the composite AgBr /CaMoO4 exhibited the higher catalytic activity than pure AgBr or CaMoO4 for the reduction of p-nitrophenol (4-NP).Moreover, the content AgBr greatly impacted the catalytic ac-tivity of composite AgBr/CaMoO4 .The conversion rate of 4-NP with AgBr/CaMoO4-5% as catalyst could reach 100%within only 4 min, which might be attributed to more available active sites from the highly well-dispersed Ag-Br nanoparticles on the surface of microspheres CaMoO 4 .In addition, the catalyst AgBr/CaMoO4 composite dis-played structure and cycle stability .The present study might provide a new strategy to design composite materials with excellent catalytic performance .关键词
