Abstract

The invention belongs to the technical field of preparation of carbon nanotube catalysts, and particularly relates to a carbon nanotube catalyst prepared by utilizing a Fenton reagent as well as a preparation method and application of the carbon nanotube catalyst. The method comprises the following steps: (1) firstly dispersing carbon nanotubes in a hydrogen peroxide solution, and then adding a metal compound to form a mixed solution; (2) reacting the mixed solution under ultraviolet light, and filtering and drying to obtain the carbon nanotube catalyst; wherein when the reaction is carried out under the ultraviolet light, the method also comprises a step of supplementing hydrogen peroxide into the mixed solution. The carbon nanotube catalyst obtained by the method has a complete structure and few defects, and metal particles in the catalyst are small and uniformly dispersed. According to the invention, the metal is uniformly loaded in the carbon nanotubes while the oxidation of the carbon nanotubes is realized, so that the process steps are simplified, the active sites of the carbon nanotube catalyst are increased, and the reaction activity of the catalyst is improved.
