摘要
采用溶胶-凝胶方法将光催化剂TiO_2和ZrO_2复合,再经700℃灼烧5h后获得了纳米复合光催化材料TiO_2-ZrO_2。该材料经XRD检测具有光催化活性良好的晶型结构。TEM测定结果显示产物的平均粒径约为20nm。通过对可溶性染料刚果红等的光催化降解实验证明,该复合材料具有较高的光催化活性。
The TiO2-ZrO2 composite was prepared by sol-gel method with baking at 700℃ for 5h,and characterized by XRD and TEM. The results show that the composite exhibits a crystalline structure with the average size of ca. 20nm. The composite shows high photocatalytic activity to decompose aqueous dye of congo red.
