Abstract

The invention discloses a preparation method of a star-shaped bismuth vanadate / boron alkene composite material, which comprises the following steps: synthesizing a star-shaped bismuth vanadate three-dimensional structure by using a hydrothermal method, and synthesizing the bismuth vanadate / boron alkene composite material by using star-shaped bismuth vanadate and boron alkene as raw materials and using the hydrothermal method. According to the preparation method disclosed by the invention, the star-shaped bismuth vanadate with uniform micron-sized morphology is obtained, and compared with an existing bismuth vanadate material with a common structure, the star-shaped bismuth vanadate prepared by the preparation method disclosed by the invention has a micron-sized size, so that a two-dimensional boron-alkene nano material can be effectively loaded, excessive stacking of boron-alkene sheets is effectively avoided, and the star-shaped bismuth vanadate / boron-alkene composite material with ordered morphology is obtained; the photocatalytic performance of the material is effectively improved.

Description

Technical field [0001] In the field of synthetic preparation method of photoelectrochemical catalytic material, the present invention relates to a method of preparing a star-shaped vanadate / bohane composite material. Background technique [0002] Since the 1970s, Professor Fujishima A. and Honda K. Two professors found titanium dioxide for the first time, two professors found titanium dioxide (TIO 2 The single crystal electrode produces hydrogen at catalytic decomposition water under ultraviolet light irradiation. This phenomenon makes it possible to directly decompose hydrogen hydrogen directly using solar energy. Thereby opening a research path using solar fluid hydrogen hydrogen production. With the increasing energy problems and environmental issues, the demand for clean energy technology has triggered a boom using nanostructures for water decomposition and environmental repair applications. So far, TIO 2 Still is a reference material for many light conversion processes. De...
