Abstract: 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.
