Amine-functionalize metal organic framework (NH2-UIO-66) was successfully synthesized by solvothermal method with zirconium salt and 2-aminoterephtalic acid. Tri-metallic RuCuMo nanoparticles (NPs) were immobilized by a facile impregnation-reduction method to prepare RuCuMo@NH2-UIO-66 catalysts. The structure, morphology, composition and specific surface area of the above catalysts were characterized. Ru1Cu2Mo0.5@NH2-UIO-66 catalyst exhibits the highest catalytic activity comparing with Ru, RuCu and CuMo counterparts as well as pure tri-metallic RuCuMo NPs in hydrolytic dehydrogenation of ammonia borane at room temperature, and the correspoding activation energy (Ea) and turnover frequency values (TOF) are 30.1 kJ?mol -1 and 180.83 mol H2 min -1(mol Ru) -1, respectively. Addition of Cu and Mo can significantly enhance the catalytic activity of Ru counterparts, owing to the synergistic effect among Ru, Cu and Mo atoms, bi-functional effect generated between RuCuMo NPs and NH2-UIO-66 support, and the amine as anchoring groups in the NH2-UIO-66 framework, which facilitate the formation and stabilization of ultra-small RuCuMo NPs by preventing their aggregation. The addition of non-noble metals Cu and Mo provides an important approach for the improvement of catalytic activity and industrial application.

Key words: metal organic frameworks (NH2-UIO-66), RuCuMo@NH2-UIO-66, solvothermal method, synergistic catalysis, releasing hydrogen
