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, N-2 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 H-2.min(-1)(mol catalyst)(-1), and 100% H-2 selectivity at 298 K. Additionally, the durability of this catalyst is very excellent for five cycles. (C) 2017 Hydrogen Energy Publications LLC. Published by Elsevier Ltd. All rights reserved.
