The preparation method of the photocatalytic material comprises the following steps: 4, 4 '-diaminodiphenylmethane and urea are subjected to heating and heat preservation treatment, and benzene ring doped and substituted g-C3N4 is obtained; and carrying out thermal etching treatment on the benzene ring doped and substituted g-C3N4 to obtain the photocatalytic material. The preparation method provided by the invention is simple andnovel in process; the preparation method is simple, the preparation cost is relatively low, and the prepared photocatalytic material is a benzene ring doped g-C3N4 nanosheet, has relatively strong light absorption capability, is an excellent carbon-nitrogen based organic visible light catalyst, is good in photocatalytic effect, does not generate pollution of heavy metal ions, and is relatively green and environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of photocatalysis, and in particular relates to a photocatalytic material and its preparation method and application. Background technique [0002] In recent years, with the increase of the global population and the consumption of traditional fossil fuels and unreasonable emissions of combustion products, the problems of environmental pollution and energy shortage are particularly serious. To solve these problems, it is necessary to promote the development and research of cleaner alternative energy sources. In this context, hydrogen appears to be a promising clean energy source. The energy density of hydrogen energy is high, and the products of combustion are non-toxic and harmless. Therefore, replacing traditional energy with hydrogen energy is an effective means to solve environmental pollution and deal with the energy crisis. Solar energy is recognized as the most potential renewable clean energy. It h...
