The invention discloses a carbon nano tube and graphite flake hybrid material and a preparation method and application thereof, belonging to the field of advanced catalytic oxidation water treatment. And pyrolyzing a certain amount of salt with central atoms as iron transition metals in a nitrogen inert atmosphere at a certain temperature, cooling, washing, etching, drying, and then performing secondary annealing to obtain the carbon nanotube and graphite sheet hybrid material. The invention takes the carbon nano tube and graphite sheet hybrid material as the catalyst, activates PMS to degrade TC and OTC, and still maintains high TC removal rate even in high salinity wastewater (anion content 500 mM). Compared with the traditional Fenton reaction, the catalyst has wide pH tolerance. The degradation product of the invention is CO 2 And H 2 O, no secondary pollution, and has the advantages of green color, high efficiency, low cost, etc. The catalyst can be prepared in large scale and has potential commercial value. |
