采用不同类型的半导体TiO2为催化剂，研究了非均相光催化氧化降解水中聚丙烯酰胺（PAM）的可行性，并对其活性进行了考察。结果表明，不同类型的半导体对PAM水溶液氧化活性不同，以纳米级的锐钛矿型TiO2活性较好，煅烧温度对制备的催化剂活性影响也不同。
The feasibility of heterogeneous photocatalytic oxidation of polyacrylamide (PAM) in water was studied using different types of semiconductor TiO2 as catalysts, and the activity was investigated. The results show that different types of semiconductors have different oxidation activities on PAM aqueous solution. The activity of nano-scale anatase TiO2 is better. The calcination temperature has different influence on the activity of prepared catalyst.
