Abstract

The invention discloses a preparation method of a hollow BiVO4 micron sheet photocatalyst. The preparation method comprises the steps of synthesizing a hollow BiVO4 micron sheet and preparing a boric acid ion doped and cobaltous oxide nano particle co-modified hollow BiVO4 micron sheet. The method has the benefits that a required raw material source is rich; a synthesis method is simple; large scale preparation can be achieved; the repeatability is good; the material stability is high; the material prepared by the method can be used for photocatalytic degradation of organic pollutants and photocatalytic decomposition of water produced oxygen, and has very good practical values and application prospects.

Description

technical field [0001] The invention relates to the technical field of inorganic functional nanomaterials, in particular to a hollow BiVO co-modified with borate ion doping and cobalt oxide nanoparticles 4 Preparation method of micron sheet photocatalyst. Background technique [0002] Environmental pollution and energy shortage have become important issues restricting the sustainable development of human society. The development of new energy and environmental purification materials has become a major issue for all mankind. Solar energy is the most ideal renewable resource. Using green sunlight to drive the degradation of organic pollutants, this photocatalytic technology has become an important means to solve environmental problems. [0003] The core of photocatalytic technology is the development of new and efficient photocatalysts. The commercial P25 photocatalyst has been widely used. However, the product has the disadvantage that the spectral response range is too n...
