Abstract

The invention discloses a boron-doped non-metal catalyst as well as a preparation method and application thereof. The preparation method comprises the following steps: adding a carbon material into anacid solution, heating and soaking the carbon material, filtering the solution, and washing the carbon material with ultrapure water, and drying the carbon material; dispersing the material into a volatile solvent, adding a boron-containing precursor, heating the material in an oil bath, washing the material with ultrapure water after the reaction is finished, and drying a product; and roasting the product in a non-oxidizing atmosphere to obtain the boron-doped non-metal catalyst. The low-toxicity boron-doped non-metal catalyst is used for replacing a high-toxicity heavy metal catalyst, has the characteristic of environmental friendliness, has a good degradation and removal effect on organic pollutants, and shows extremely high catalytic activity and a wide application range.

Description

technical field [0001] The invention relates to the technical field of catalyst materials, in particular to a boron-doped non-metallic catalyst and its preparation method and application. Background technique [0002] In recent decades, with the rapid development of industry and the improvement of people's living standards, many new chemicals have continuously entered the environment. These pollutants have the characteristics of low concentration, high toxicity, and refractory biodegradation, which are difficult to remove through conventional treatment techniques. May cause serious impact on the ecological environment. The advanced oxidation technology based on sulfate radical is a kind of strong oxidizing sulfate radical (SO 4 ●− ) The water treatment technology for degrading organic pollutants has the advantages of environmental friendliness, simple equipment and fast response, and has great application potential in water treatment, soil remediation, sludge disposal and ...
