High Catalytic Performance of MIL-101-Immobilized NiRu Alloy Nanoparticles towards the Hydrolytic Dehydrogenation of Ammonia Borane

Ultrafine NiRu alloy nanoparticles (NPs) were successfully immobilized on MIL-101 for the first time by the double-solvent method combined with the overwhelming reduction approach. The NPs were fully characterized by transmission electron microscopy, powder X-ray diffraction, energy-dispersive X-ray spectroscopy, and X-ray photoelectron spectroscopy. The MIL-101-immobilized NiRu alloy NPs exhibited much higher catalytic activity toward the hydrolytic dehydrogenation of ammonia borane than the pure NiRu alloy NPs and Ni@Ru core-shell NPs.
