The development of highly efficient and cheap catalysts for the release of hydrogen from chemical hydrogen-storage materials is indispensable for the coming clean energy economy. ZIF-67 is transferred into oxygen-doped porous carbon (OPC-300) using two-step heat treatment for the first time. The OPC-300 nanomaterial appears much more effective than other supports, including ZIF-67, graphene oxide and MOF-74, for Ni 0.66 Co 0.19 P 0.15 nanoparticles. NiCoP/OPC-300 nanocatalysts, obtained for the first time, have been successfully synthesized via...
