Abstract
In this paper, CeVO 4 /FeVO 4 nanocomposites were prepared by direct feeding microwave synthesis method with nine water iron nitrate (Fe(NO 3 )3 • 9H 2 O), cerium nitrate hexahydrate (Ce(NO 3 )3 • 6H 2 O) and ammonium metavanadate (NH 4 VO 3 ) as raw material and Sodium Dodecyl Sulfate (SDS) as surfactant. Then X-Ray Diffractometer (XRD) and Scanning Electron Microscopy (SEM) were used to observe the CeVO 4 /FeVO 4 nanocomposites. SEM image showed that the as-prepared CeVO 4 / FeVO 4 nanocomposites calcined at 773 Kis formated of small particles aggregation irregular sheet structure. We studied the photocatalytic activity of the as-prepared samples by using degradation of methyl orange in visible light. The results showed that the photocatalytic activity of CeVO 4 /FeVO 4 nanocomposites were very well. It found that when the catalyst calcined at 773 K was 0.10 g, and 0.5 mL hydrogen peroxide joined as well as, pH was 2.0, the degradation ratio of catalyst for methylene orange of 100 mL 5 mg/L reached 98.63% in 40 min.
