摘要: CeO2 nanoparticles were prepared by a simple precipitation method, followed calcination treatment. By selecting photocatalytic degradation of acid orange 7 (AO7) as probe reaction, the influences temperature catalyst, concentration AO7, initial pH value AO7 solution and catalyst dosage on activity studied. It was found that calcined at 550°C shows highest under visible light irradiation. revealed irradiation over follows dye self-sensitization mechanism. The rate increases with decrease in reaction solution, efficiency decreases increase concentration. optimal for is 1 g/L.
