细菌纤维素负载稀土掺杂二氧化钛复合膜的制备和光催化性能
Keywords: 复合材料,？细菌纤维素,？稀土,二氧化钛,光催化,甲基橙
Abstract:
？以细菌纤维素(bc)为载体,用溶胶－凝胶法原位生成稀土镧和铈元素(la,ce)掺杂的二氧化钛复合膜,以甲基橙为目标降解物,考察了复合膜的光催化活性。结果表明:稀土元素已引入tio2/bc复合膜中;掺杂tio2的晶型为锐钛矿型;掺杂稀土的tio2/bc复合膜的光催化活性比未掺杂的有较大提高;铈掺杂的tio2/bc复合膜的光催化性能优于镧掺杂的;ce4+掺杂的最适浓度为2mmol/l,而la3+掺杂的最适浓度为5mmol/l;稀土掺杂的tio2/bc复合膜对甲基橙溶液重复降解5次的降解率仍高于70%。
