摘要
采用共沉淀法制备了一系列铋铁复合氧化物光催化剂,并以可见光降解甲基橙为模型反应,研究其在可见光照射下降解甲基橙的光催化性能。详细考察了p H值、铋铁摩尔比、煅烧温度等对其光催化性能的影响。在优化条件下,铋铁摩尔比为2∶1、p H=3~4时制备出的样品具有较好的光催化性能,甲基橙的降解率可达到91.95%。
This paper introduced a series of Bismuth and iron compound oxides photocatalysts were prepared by coprecipitation method, and the visible light degradation of methyl orange as a model reaction, photocatalytic performance of the degradation under visible light irradiation of methyl orange. Effects of p H value, bismuth and iron molar ratio, calcination temperature on the photocatalytic properties were investigated in detail. Under the optimized conditions, bismuth and iron molar ratio was 2∶1, the prepared samples in p H=3~4 had better photo catalytic degradation of methyl orange, the degradation rate could reach 91.95%.
