Synthesis and Photocatalytic Property of FeVO4 Photocatalyst by Sol-Gel Method

Abstract:

FeVO4 photocatalysts were synthesized by complexing Sol-Gel method using citric acid as chelate and characterized with X-ray diffraction (XRD), scanning electron microsoope(SEM, specific surface area (BET). The photocatalytic activity was evaluated by photocatalytic degradation of methyl orange (MO) solution under visible light. It was found that the sample prepared with the molar ratio of citric acid to metal inons be 2:1, pH=7 and calcinated under 750°C for 4 hours was pure triclinic FeVO4 phase. In the experimental conditions used, the FeVO4 calcined at 750°C had highest photocatalytic activity with the photodegradation rate was about 85% or so in 150min under 250W halogen lamp.
