Abstract
The invention relates to a metal monatomic catalyst as well as a preparation method and application thereof, and belongs to the field of environmental protection. According to the preparation method of the metal monatomic catalyst, MAX-based ceramic powder with the chemical formula of Mn + 1AXn and inorganic salt powder of metal B are taken as raw materials, and the metal monatomic catalyst is prepared by using According to the method, anchoring preparation of the monatomic catalyst is achieved through a one-step method, and complex doping treatment does not need to be conducted on the carrier. Compared with an existing method for activating persulfate through transition metal ions and compounds of the transition metal ions, the method has the advantages that the adding amount of transition metal is remarkably reduced, and the problems of metal ion leakage, effluent chromaticity increase and sludge disposal can be solved.
