Supported RuM nano-alloy catalyst and preparation method thereof

The invention relates to the technical field of catalytic application, and discloses a supported RuM nano-alloy catalyst and a preparation method thereof.Oxides such as SiO2 and Al2O3 serve as carriers, the pH of a metal precursor solution is adjusted through ammonia water, meanwhile, the metal precursor solution and metal ions form an ammonia complex, the strong electrostatic adsorption theory is utilized, and the supported RuM nano-alloy catalyst is prepared. Enabling the metal-ammonia complex with positive charges to be strongly and uniformly adsorbed on the surface of the carrier enriched with negative charges, and reducing the catalyst precursor in a reducing atmosphere to obtain the RuM nano-alloy catalyst. According to the method, the strong electrostatic adsorption effect of the precursor and the carrier can effectively inhibit the agglomeration phenomenon of the nanoparticles at high temperature, the size control of the RuM nanoparticles loaded on the carrier can be realized, and the uniform distribu
