Carbonized bacterial cellulose-cadmium sulfide composite photocatalytic material as well as preparation method and application thereof

Abstract

The invention relates to a carbonized bacterial cellulose-cadmium sulfide composite photocatalytic material as well as a preparation method and application thereof. The photocatalytic material is prepared by using the following methods: 1) inoculating Gluconacetobacter xylinus into a culture medium A, carrying out dynamic culture for 96 hours, collecting a bacterial cellulose product, washing, drying, and further carrying out vacuum freeze drying so as to obtain bacterial cellulose aerogel; 2) dissolving a fixed amount of thiourea and cadmium sulfide into ultrapure water, adding a proper amount of the bacterial cellulose aerogel, and carrying out a hydrothermal reaction at a high temperature and high pressure; 3) carrying out high-temperature calcining on the bacterial cellulose aerogel-cadmium sulfide compound product in a tubular furnace, thereby obtaining the carbonized bacterial cellulose-cadmium sulfide composite photocatalytic material. The preparation method provided by the invention has the advantages of being simple in operation, low in cost, and the like. The obtained carbonized bacterial cellulose-cadmium sulfide composite photocatalytic material can be used as a catalyst in water hydrogen generation of photocatalysis splitting.

Description

technical field [0001] The invention relates to a carbon fiber-cadmium sulfide composite photocatalytic material and its preparation method and application. Background technique [0002] Since the 21st century, with the rapid development of science and technology, productivity has been significantly improved, creating huge wealth for human beings. While people use science and technology to create wealth, they also bring a series of problems such as excessive energy consumption and serious damage to the ecological environment. Faced with this situation, heterogeneous photocatalytic technology using semiconductors and renewable solar energy is considered as one of the most promising processes to alleviate or even solve the world's energy supply crisis and environmental pollution. Water-splitting photocatalytic hydrogen production technology has been favored by a large number of researchers because of its environmental friendliness, renewable reuse and other advantages. As a ...
