摘要: 采用沉淀-浸渍法制备了不同负载量的二氧化硅负载碘氧化铋催化剂,考察了其光催化降解甲基橙性能。采用XRD、UV-Vis、TEM对催化剂进行了表征。结果表明,随着碘氧化铋负载量的增加,二氧化硅负载碘氧化铋催化剂光催化降解甲基橙的降解率升高。当碘氧化铋和二氧化硅的物质的量比为0.5时,二氧化硅负载碘氧化铋催化剂降解甲基橙的降解率60 min时可达73.74%。不同粒径二氧化硅负载的碘氧化铋催化剂对甲基橙的降解率接近,因为活性组分碘氧化铋都可以高度分散在不同粒径的二氧化硅载体上。

Abstract: BiOI/SiO2 catalysts with different loadings were prepared by precipitation?鄄impregnation method,and their performance of photocatalytic degradation of methyl orange was investigated.The catalyst was characterized by XRD,UV-Vis and TEM.The results showed that the photocatalytic degradation rate of methyl orange by BiOI/SiO2 catalyst increased with the increase of BiOI loading.When the amount?鄄of?鄄substance ratio of BiOI to SiO2 was 0.5,the degradation rate of methyl orange by BiOI/SiO2 catalyst could reach 73.74% in 60 min.The degradation rate of methyl orange of BiOI supported on SiO2 with different particle sizes was almost similar,because the active component BiOI could be highly dispersed on SiO2 supports with different particle size.

Key words: SiO2;BiOI;photocatalytic;methyl orange
