The invention discloses a molybdenum phosphide composite catalyst and a preparation method thereof. The catalyst comprises a nitrogen and phosphorus co-doped carbon nanosheet, and molybdenum phosphide nanoparticles are loaded on the nitrogen and phosphorus co-doped carbon nanosheet. The preparation method comprises the following steps: preparing a molybdenum-based metal organic framework/melamine dispersion liquid, and then adding a phytic acid solution for solvothermal reaction and calcination. The molybdenum phosphide composite catalyst has the advantages of being high in catalytic activity, good in stability and the like, can be widely used for removing sulfur-containing organic compounds in petroleum products, can achieve efficient removal of the sulfur-containing organic compounds in the petroleum products under mild conditions, and has very high use value and very good application prospects. The preparation method of the molybdenum phosphide composite catalyst has the advantages of being simple in proce
