Low loading of metal in metal-organic framework-derived NiNx@NC promotes amide formation through C–N coupling

The pyrolysis of Ni-substituted zeolitic imidazolate framework-8 produces NiNx@NC with a ultra-low loading of Ni (7.4 x 10-6 mol%). The Ni–N coordination, subnanometer particle size, and uniform distribution of NiNx...
