Abstract

The invention provides a gold nano-particle-bismuthous sulfide heterojunction nanometer photocatalysis material, a preparation method thereof and application of the gold nano-particle-bismuthous sulfide heterojunction nanometer photocatalysis material in degrading of pollutants. The preparation method comprises the following steps: (1) preparing a sulfur-containing solution, namely, degassing 1-octadecene at the atmosphere of argon, and uniformly mixing the 1-octadecene subjected to degassing and bis(trimethylsilyl) sulfide; (2) preparing a gold-containing solution, namely, mixing oleylamine and HAuCl4, degassing, and carrying out heating reaction under the condition of stirring until the mixture is wine red; (3) preparing a bismuth-containing solution, namely, mixing Bi(OAc)3, oleic acid and 1-octadecene, and dissolving Bi(OAc)3; (4) mixing the sulfur-containing solution and the gold-containing solution, adding a mixture in the bismuth-containing solution, heating, and annealing; and (5) adding excess acetone solution, and purifying to obtain a composite, linking to the middle part of a bismuthous sulfide one-dimensional nano-rod, of gold nano-particles. The gold nano-particle-bismuthous sulfide heterojunction nanometer photocatalysis material is good in photo catalytic degradation and photosensitivity, has the inactivation to bacteria and can be applied to the environment field of improving water quality.

Description

technical field [0001] The invention relates to a heterojunction visible light photocatalytic material, in particular to a heterojunction nanorod photocatalytic material with high catalytic reduction ability for dyes and a preparation method thereof. Background technique [0002] In recent years, the development and application of new photocatalytic materials has gradually become a research hotspot at home and abroad. Photocatalytic materials have shown excellent performance and great potential in alleviating energy crisis and environmental pollution. Among them, heterojunction nanomaterials realize the transfer of photo-induced electrons and holes between different materials through the connection between semiconductors and semiconductors, semiconductors and metal materials, and promote light absorption and suppress photo-generated electrons-holes. It has excellent performance in acupoint compounding and other aspects, so it has received extensive attention. However, most ...
