摘　　要：以自制N-甲基-N-硝基苯基吗啉盐酸盐离子液体为介质,以TiOCl2溶液为前驱体,利用低温水解法制备了金红石型纳米TiO2粉体.结果表明,所制TiO2粒径为4.7 nm,将其用于光催化降解甲基橙,5 h内甲基橙降解率可达99.18%,说明其具有优良的光催化性能.The rutile nanometer TiO2 powder was prepared using self-made N-methy-N-nitrophenyl morpholine hydrochloride ionic liquid as the medium and TiOCl2 solution as the precursor by low temperature hydrolysis method. The results show that the prepared TiO2 particle size is 4.7 nm. The nanometer TiO2 was used in photocatalytic degradation of methyl orange. The results show that the degradation rate can reach 99.18% in 5 h, which shows that the prepared nanometer TiO2 has excellent photocatalytic performance.
