摘 要: 采用多种方法制备杂多酸盐异构体/聚苯胺掺杂材料(SiW11Co/PANI),利用紫外光谱对产物的结构进行表征,并对其光催化活性进行研究。实验过程中通过光照时间、催化剂用量、溶液初始浓度、不同光源、溶液初始pH值等条件变化对染料次甲基蓝的影响,确定最佳催化条件,分析最佳制备方法,并初步考察染料的分解模式。结果表明:固相(有酸的条件)法合成的SiW11Co/PANI具有较好的光催化性能。
关 键 词: 分析化学;杂多酸盐;光催化;染料

Abstract: Polyoxometalate isomers/polyaniline (SiW11Co/PANI) was prepared by various methods. The products were characterized by means of ultraviolet (UV) spectrum, and the photocatalyst properties of the products were studied. In the experiments, the removal efficiencies to methylene blue under different conditions, such as illumination time, catalyst content, initial concentration of the solution, light sources and pH values were studied, the best catalyzing condition was determined, the best preparation method was analyzed, and the decomposition of the dye was researched. The results showed that the SiW11Co/PANI synthesized under solid method with acid had good photocatalytic properties.
Key words: analytical chemistry; polyoxometalates; photocatalysis; dye
