摘要
采用原位化学氧化聚合法制备了一系列不同酸掺杂和不同氧化剂用量的PANI/TiO2复合光催化材料,利用IR对其结构进行表征,并研究了该系列光催化材料在可见光下对甲基红的降解情况。通过研究表明当苯胺与TiO2的质量比为5:1,AN与APS摩尔比为2:1时,可见光催化活性较好;硫酸掺杂的PANI/TiO2可见光催化活性较好。
A series of PANI/TiO2 photocatalyst powders doped with different acid and different amount of oxidant were successfully prepared by in situ chemical oxidation polymerization, and characterized by Infrared Ray. Degradation of organic dye methyl red under Visible light catalyzed by the prepared catalyst was studied. Results showed that when the mass ratio of aniline（AN） to titania（TiO2） was 5 ： 1,the molar ratio of AN to APS was 2 ： 1,the catalyst was of good photocatalytic activity. It was also found that the PANI/TiO2 composite photocatalysis material doped with sulfuric acid had stronger photocatalytic activity.
