【 摘 要 】

Nanosize Cu-doped FeVO4 was prepared by microwave-assisted method and was used as photocatalyst in the degradation of simulated wastewater like methyl orange. The effects of light intensity, amounts of H2O2 and FeVO4:Cu2+ on the degradation efficiency were studied. The result showed that under the optimized conditions, with an 800w xenon lamp, 0.09g of FeVO4:Cu2+ and 0.3mL of 3%H2O2, the degradation rate of methyl orange (30mL, 10mg/L) reached 94% after 180 min of viable light irradiation.
