Abstract:
By adjusting various RuM(M=Co,Ni) molar rations, a series of highly dispersed bimetallic RuM alloy nanoparticles (NPs) deposited on MIL-110(Al) have been successfully prepared via a conventional impregnation-reduction method. The catalytic properties of RuM@MIL-110 were investigated by hydrolytically releasing H2 from AB at room temperature. The results reveal that the as-prepared Ru1Co1@ MIL-110 and Ru1Ni1@MIL-110 exhibit the highest catalytic activity in different RuCo and RuNi molar rations, respectively, owing to the bimetallic synergistic actions between Ru and M, uniform distribution of metal NPs as well as bi-functional actions between RuM alloy NPs and MIL-110. The turnover frequency (TOF) values of the Ru1Co1@MIL-110 and Ru1Ni1@MIL-110 catalysts are determined to be 533.2 and 454.7 mol H2 min-1 (mol Ru)-1 and the activation energies (Ea) are 31.7 and 36.0 kJ mol-1, respectively. Moreover, these catalysts exhibit favorable stability after 5 consecutive cycles for the hydrolysis of AB.
