Exploitation of high-efficiency and low-cost catalysts for dehydrogenation of the ideal hydrogen storage material (ammonia borane) can effectively promote the development of hydrogen economy. Here, we report an efficient and economical non-noble-metal magnetic catalyst (Ni0.23Co0.19P0.58@NHPC90 with nanoparticles uniformly distributed on MOF-derived (metal-organic framework) nitrogen-doped hierarchical porous carbon (NHPC90 by a one-step in situ synthesis method. The catalyst has achieved a superior initial total turnover frequency (
