Preparation of Fe3O4/TiO2 and its Photocatalytic Performance

摘要：

Aimed at the problem solving of difficult reclaiming nanometer TiO2, the paper conducts a study on magnetic recovering by a series of experiments. Firstly, taking methylene blue as the object, the test compares the photocatalytic performance between self-manufactured TiO2 and commercial TiO2 after 160 minutes photocatalytic degradation. The results show that their degradation rates are 94% and 99% respectively, which indicates the photocatalytic performance of selfmanufactured TiO2 is feasible. Secondly, the test prepares Fe3O4 magnetic nucleus adopting titration-hydrolysis method, use them to magnetize the photocatalytic material self-manufactured TiO2, and then verifies the magnetism of self-manufactured TiO2. The result manifests that self-manufactured TiO2 possesses great magnetism and can be reclaimed effectively with magnetic separation technique. However, after undergoing 160 minutes photocatalytic degradation, its degradation rate is only 32.68％, which denotes that its photocatalytic degradation performance is low.
