摘要
为解决光催化剂在降解过程中回收困难、易造成水体二次污染的难题,以聚多巴胺为媒介,采用原位合成法,在棉织物上生长二氧化钛(TiO_(2)),并负载银(Ag)纳米粒子,制备织物基Ag/TiO_(2)光催化材料。结果表明,织物基Ag/TiO_(2)光催化材料在可见光照射210 min时,对亚甲基蓝的去除率达到85.6%。此外,该材料还具有优异的抗菌性能。
In order to solve the problem that photocatalysts are difficult to recovery during degradation and easy to cause secondary pollution of water,the fabric-based Ag/TiO_(2)photocatalyst material is prepared by in-situ synthesis of titanium dioxide(TiO_(2))on cotton fabric and loading silver(Ag)nanoparticles by using polydopamine as the medium.The results show that the removal rate of Methylene Blue by fabric-based Ag/TiO_(2)photocata⁃lytic material reaches 85.6%when exposed to visible light for 210 min.In addition,the material has excellent an⁃timicrobial properties.
