CoRh nanoparticles supported on ZIF-67 as highly efficient catalysts for hydrolytic dehydrogenation of ammonia boranes for chemical hydrogen storage

Extremely diffused bimetallic CoRh nanoparticles supported on ZIF-67 have been triumphantly compounded by using a simple wet-chemical approach and then they were characterized by ICP-AES, power XRD, N2 adsorption-desorption, HTEM, EDX, SEM and XPS. In the midst of the texted catalysts, the catalytic activity of the Rh25Co75@ZIF-67 catalysts is the highest, with turnover frequency (TOF) value of 100.21mol H2.min−1(mol catalyst)−1, and 100% H2 selectivity at 298 K. Additionally, the durability of this catalyst is very excellent for five cycles.
