▎ 摘　　要

NOVELTY - Preparation of bimetallic catalyst involves dispersing stabilizer, pore-forming agent and activator in reaction medium to form an activation solution, where the activator contains first metal ion, uniformly mixing carrier with the activation solution and carrying out crystallization treatment to obtain an activated carrier, uniformly mixing the activated carrier with the metal ion solution with catalytic activity, drying and calcining to obtain a precursor, where the catalytically active metal ions include noble metal ions and second metal ions, and reducing the precursor. USE - Preparation of bimetallic catalyst used in hydrogenation and dehydrogenation reactions of organic hydrogen storage material (all claimed). ADVANTAGE - The method controls preferential substitution of active sites of the catalyst and simultaneously controls to synthesize high-dispersion degree catalyst with excellent stability, through activation treatment of the carrier based on lattice confinement effect and surface reticulated hydrazine structure, and reduces load amount of noble metal, improves stability of the catalyst, saves production and use cost of the catalyst. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) bimetallic catalyst; and (2) Hydrogenation and dehydrogenation method for an organic hydrogen storage material, which involves: (a) heating and reacting the organic hydrogen storage material and the bimetallic catalyst in a closed system under hydrogen atmosphere.
