Abstract

The invention provides a nanometer clavate nonmetallic doped BiPO4 photocatalyst and a preparation method as well as an application of the nanometer clavate nonmetallic doped BiPO4 photocatalyst. The preparation method comprises the following steps: dissolving a Bi source, a P source and doped matter into water, stirring uniformly, adjusting the pH value to be faintly acid so as to form a precursor; putting the precursor into a microwave hydrothermal reaction kettle, putting the microwave hydrothermal reaction kettle into a microwave hydrothermal instrument, reacting by adopting a microwave hydrothermal method until reacting completely, taking out the generated precipitate after reaction, washing and drying so as to obtain the nanometer clavate nonmetallic doped BiPO4 photocatalyst. According to the invention, the nanometer clavate nonmetallic doped BiPO4 photocatalyst is synthesized by the microwave hydrothermal method by one step; the process is few, the operation is simple, the reaction time is short, and the reaction condition is mild; the synthesized nanometer clavate nonmetallic doped BiPO4 photocatalyst has relatively high photocatalytic activity, achieves the aim of modifying BiPO4, and can be applied to environment pollutant degradation.

Description

technical field [0001] The invention belongs to the field of functional materials, in particular to a nanorod-shaped non-metal doped BiPO 4 Photocatalyst and its preparation method and application. Background technique [0002] The environmental pollution caused by the rapid development of today's society has become a problem that people pay more and more attention to. How to solve various pollution problems faced by human society has become an important issue. In recent years, photocatalytic oxidation technology has been extensively studied by scholars in the field of environmental research due to its strong ability, high efficiency, and no secondary pollution to treat organic pollutants. At present, bismuth-based semiconductors and their inorganic compounds have attracted extensive attention because of their good photoelectric conversion efficiency, stable photochemical properties, strong light absorption ability, and significant oxidation ability to toxic organic polluta...
