A preparing method of an ordered mesoporous carbon-supported Ru nanometer catalyst

A preparing method of an ordered mesoporous carbon-supported Ru nanometer catalyst is disclosed. The method includes a step of dissolving ruthenium chloride into ethanol to prepare a ruthenium chloride solution, a step of adding a certain amount of F127 into ethanol, stirring in a water bath, adding a certain amount of phenolic resin, the ruthenium chloride solution and an ethanol solution of 8-hydroxyquinoline in order, mixing, stirring, pouring into a petri dish and evaporating to dryness, a step of performing thermal polymerization, and a step of putting into a tubular furnace and calcinating in a N2 atmosphere at 700-900 DEG C to obtain the catalyst. The composite catalyst prepared by the method is a mesporous Ru/OMC material with ultra-small particles (1-2 nm), a high specific surface area (495-643 m2/g) and ordered pore diameter distribution. The method is characterized by a simple process, a low cost, high purity, the high specific surface area, regular and ordered pore path structures, narrow pore diameter distribution, and the like.
