Description

technical field

[0001] The technical field of the invention is photocatalyst, in particular, it belongs to magnetically separable photocatalyst and its preparation method. Background technique

[0002] As we all know, with the development of industry, the problem of environmental pollution has become very serious, and solving the problem of pollution is an important content and task of current scientific research.

[0003] Semiconductor photocatalysis technology uses ultraviolet light to irradiate photocatalytically active semiconductor materials to initiate photocatalytic reactions. TiO 2 Photocatalytic material is a semiconductor photocatalytic material that has received extensive attention in recent years. A large number of studies have shown that dyes, surfactants, organic halides, pesticides, oils, cyanides, etc. can be destroyed by TiO 2 Effectively complete photocatalytic degradation, decolorization, detoxification, and mineralization into small inorganic molecules...
