Abstract

The invention relates to Ag3PO4 / g-C3N4 composite tubular nano powder and a preparation method thereof, and relates to the technical field of preparation of composite materials for new energy and environmental sewage restoration. The Ag3PO4 / g-C3N4 composite tubular nano powder is prepared from g-C3N4 particles and silver phosphate nanoparticles, and the silver phosphate nanoparticles are uniformlyattached to pipe walls and pipe orifices of the tubular g-C3N4 particles. The preparation method comprises the steps of firstly dissolving cyanuric chloride, melamine and urea in an acetonitrile solvent, uniformly stirring and mixing, carrying out solvothermal method reaction, and obtaining g-C3N4 tubular nano powder through aftertreatment; secondly, ultrasonically dispersing the g-C3N4 powder inabsolute ethyl alcohol, adding sodium dihydrogen phosphate and silver nitrate, carrying out ultrasonic in-situ precipitation reaction, and obtaining the Ag3PO4 / g-C3N4 composite tubular nano powder through aftertreatment. The series-experiment result shows that the Ag3PO4 / g-C3N4 composite tubular nano powder has the characteristics of narrower particle size distribution, uniform morphology distribution, particle size controllability and the like. The composite powder has the excellent ability on visible-light catalytic degradating organic pollutants in environmental sewage.

Description

technical field [0001] The invention relates to the technical field of preparation of composite materials suitable for new energy and environmental sewage restoration, in particular to an Ag 3 PO 4 / g -C 3 N 4 Composite tubular nanopowder and its preparation method. Background technique [0002] Since 1989, Liu and Cohen of the University of California theoretically proposed β-C 3 N 4 Since covalent crystals, carbonitrides have attracted the attention of scientists from all over the world because of their excellent properties in optics and mechanics. C 3 N 4 There may be five structures, namely α phase, β phase, cubic phase, quasi-cubic phase and graphite-like phase. where g-C 3 N 4 It is the most stable phase at room temperature, and has properties such as non-toxicity and visible light response (semiconductor band gap 2.7eV), making it have broad application prospects in the field of catalysis. g-C 3 N 4 It has a typical graphite-like layered structure.
