The invention provides a supported transition metal carbide and a preparation method and application thereof, belonging to the technical field of catalysts. The preparation method of the supported transition metal carbide comprises the following steps: dissolving a carbon source and a transition metal salt in a solvent, preparing a metal-organic framework precursor through a solvothermal reaction, and then carbonizing it. When the supported transition metal carbide of the present invention is used as a catalyst to catalyze the ozone oxidation reaction of organic substances in water, a free radical reaction is initiated, the removal rate of organic substances in sewage is fast, the removal rate is high, and the salinity is high, and the water can be non-selectively catalyzed to oxidize complex species. At the same time, when it is used as a catalyst, the ozone oxidation reaction can be carried out at room temperature, with short time consumption and low energy consumption; in addition, the supported transition metal carbide has a simple preparation process and is easy to shape. As a catalyst, the supported transition metal carbide can alleviate environmental and energy problems, has strong practicability, and has a good market prospect. |
