Bimetallic RuCo nanoparticles (NPs) were successfully deposited on the highly porous and hydrothermally stable nanofibrous metal-organic framework MIL-96(Al) by using a simple liquid impregnation strategy, and the powder XRD, FT-IR, BET, TEM, EDX, ICP-AES and XPS were employed to characterize the structure, size, composition and loading metal electronic states of the RuCo@MIL-96 catalysts. The catalytic property of RuCo@MIL-96 for hydrogen generation from the hydrolysis of ammonia borane (AB) at room temperature was investigated. The results show that Ru1Co1@MIL-96 exhibits much enhanced catalytic activity compared with monometallic Ru, Co counterparts loadings and RuCo NPs due to the uniform distribution of metal NPs and synergetic effect between Ru and Co particles as well as bifunctional effects between RuCo NPs and the host of MIL-96. The turn over frequency (TOF) value of the Ru1Co1@MIL-96 catalyst is determined to be 320.7 mol H-2 min(-1) (mol Ru)(-1), which is higher than most of the reported TOF values for the same reaction, and the activation energy (Ea) is 36.0 kJ mol(-1). Moreover, this catalyst exhibits satisfied durability after five cycles for the hydrolytic dehydrogenation of ammonia borane. (C) 2016 Elsevier B.V. All rights reserved.
