A series of nonprecious metal nanoparticles (NPs) supported by metal–organic framework MIL-101 were synthesized using four methods and their catalytic performance on hydrogen evolution from ammonia borane (NH3BH3) was studied. The results showed that the crystalline Co NPs with size of 4.5–8.5 and 1...
