摘要
以四氯化钛为原料,采用沉淀法制备复合粒子TiO2/CNTs,通过正交试验得出最佳负载条件:原料液浓度为0.3mol/L、氨水滴加速度为3mL/min、溶液pH值为4、煅烧温度为400℃时二氧化钛能够均匀紧密地负载到碳纳米管表面;利用FTIR、XRD和SEM等对所制备的复合粒子TiO2/CNTs进行表征分析,结果表明,负载的二氧化钛粒子粒径为5nm左右,且所负载的二氧化钛晶形大部分是锐钛晶型。
Taking TICl4 as raw material, TiO2/CNTs compound particles were prepared by the precipitation method. The optimum conditions were obtained by the orthogonal experiment： TiCl4 solution concentration was 0.3mol/L, the dropping speed of ammonia was 3 mL/min and the pH value was 4. As the calcination temperature was 400, TiO2 could be adsorbed on the surface of carbon nanometer tube evenly and tightly. The TiO2/CNTs compound particles prepared were characterized by FTIR, XRD and SEM. The results showed that the diameter of TiO2 adsorbed was about 5nm, and the crystal phase was mostly crystal phase of anatase.
