摘　　要：以钛酸丁酯为主要原料，采用溶胶一凝胶法制备纳米TiO2粉体。以罗丹明B为降解对象，确定制备条件。结果表明：以乙醇为溶剂、醋酸为催化剂、pH值=2～3、陈化时间为1天。通过XRD检测，可知所制得纳米TiO2多为锐钛矿型。Nano TiO2 photocatalytic was prepared by sol-gel method with butyl-titanate as the raw material. The optimum conditions were determined by degradating Rhodamine B. The results show that ethanol was solvent, acetic acid was catalyst, pH=2-3, aging time was 1 days. The nano TiO2 was characterized as anatase by XRD test.
