Bimetallic Nickel–Rhodium Nanoparticles Supported on ZIF‐8 as Highly Efficient Catalysts for Hydrogen Generation from Hydrazine in Alkaline Solution

Abstract Highly dispersed bimetallic Ni–Rh nanoparticles with an average diameter of (1.2±0.2) nm were successfully deposited on the metal–organic framework (MOF) ZIF‐8 by using a simple liquid impregnation method. These catalysts were composition dependent toward the dehydrogenation of hydrazine in alkaline solution, whereas Ni 66 Rh 34 @ZIF‐8 exhibited the highest catalytic activity among all the catalysts tested with a turnover frequency value of 140 h −1 and 100 % hydrogen selectivity at 50 °C. The excellent catalytic performance may be caused by the synergistic molecular‐scale alloying effect of the bimetallic Ni–Rh nanoparticles on ZIF‐8 and the promotion effect of ZIF‐8. The development of high‐performance catalysts by utilizing MOFs as a novel porous catalyst support to control the limited growth of metal nanoparticles may promote the application of hydrous hydrazine as a promising chemical hydrogen‐storage material and open up new opportunities to use MOF‐supported metal nanoparticles for more applications.
