Performance Photocatalytic Degradation of Methomyl onto Composite Graphene Oxide/Bismuth Vanadate (GO/BiVO_4) Nanoparticle

摘要

Graphene oxide (GO) powder was synthesized by modified Hummer's method. Bismuth vanadate (BiVO_4) nanoparticle was synthesized by solvothermal method at 100 and 200°C for 3h. Composite graphene oxide and bismuth vanadate (GO/BiVO_4) nanoparticle were synthesized by mixed oxide method in weight ratio of 0.20:1.00. The physical and chemical properties were characterized by X-ray diffractometer (XRD), scanning electron microscope (SEM), energy dispersive X-ray spectrometer (EDS) and surface area analyzer (BET). The photocatalytic degradation of methomyl performance was determined by high performance liquid chromatograph (HPLC). Composite GO/BiVO_4 nanoparticle at 200°C for 3h was the highest photocatalytic degradation of methomyl.
