Abstract

The invention relates to a preparation method and application of a C3N5 material, and belongs to the technical field of photocatalysis. The technical problem to be solved by the invention is to provide the preparation method of the C3N5 material. The method comprises the following steps: a, uniformly mixing 3-amino-1,2,4-triazole and a six-membered nitrogen heterocycle according to a weight ratioof the 3-amino-1,2,4-triazole to the six-membered nitrogen heterocycle of 1:(0.8-1.2) to obtain uniformly-mixed powder, wherein the six-membered nitrogen heterocycle is at least one selected from cyanuric acid and barbituric acid; and b, heating the uniformly-mixed powder, performing heat preservation at 480-520 DEG C for 2.5-3.5 h, performing cooling, taking out the cooled material, performing washing, and performing drying to obtain the C3N5 material. According to the method provided by the invention, when the C3N5 material is prepared, the mixture of the 3-amino-1,2,4-triazole and the specific six-membered nitrogen heterocycle is adopted as a raw material, the preparation method is simple, and the C3N5 material obtained by the method has better photocatalytic activity and can be widelyused as a photocatalyst.

Description

technical field

[0001] The present invention relates to C 3 N 5 The material and its preparation method and application belong to the technical field of photocatalysis. Background technique

[0002] Photocatalytic technology is a technology that uses photocatalysts to catalyze reactions under light irradiation. It is a green technology that has important application prospects in the fields of energy and the environment. Photocatalyst is the key to photocatalytic technology. It is a general term for chemical substances that can play a catalytic role under the excitation of photons. Semiconductor photocatalysts can be excited to generate electrons and holes under the irradiation of light, and redox reactions occur on the semiconductor surface. So as to realize the decomposition of water or the decomposition of organic pollutants, and realize the utilization and conversion of light energy.

[0003] As a new type of semiconductor material, C 3 N 5 It has become a research h...
