摘要
以膨胀珍珠岩为载体,采用低温水解工艺制备了负载型纳米-TiO2/膨胀珍珠岩复合光催化材料。应用XRD、SEM、TEM、EDS等现代测试手段对复合材料的结构和性能进行了表征,并在表征和分析基础上从微观上探讨了复合粉体材料的制备机理。结果表明,纳米TiO2能均匀负载于膨胀珍珠岩载体颗粒表面,大小约为8 nm;复合材料对罗丹明B的降解率达95%以上。
Using expanded perlite as the cartier, a kind of composite photocatalyst was prepared by hydrolysis precipitation method. The obtained composite material was characterized by XRD, SEM, TEM. Based on the experimental results and analysis of characterization, the preparation mechanism of composite powder material was studied. The photocatalytic degration experiment of Rhodamine-B indicates that the expanded perlite which can combine with the TiO2 particles tightly is an ideal material to load the photocatalyst. The photocatalytic activity of the composite material is stable and constant.
