Summary:Highly dispersed ultrafine NiIr nanoparticles with different compositions were successfully encapsulated into the cavities of MIL-101 and applied to catalyze the dehydrogenation of hydrazine monohydrate. The catalytic activities relied on the composition of metals, support materials, alkaline, as well as the temperature strongly. Among all the catalysts tested, Ni85Ir15@MIL-101 exhibited the highest catalytic performance in the presence of NaOH at 50 °C. Even at 25 °C, the Ni85Ir15@MIL-101 exhibited the complete dehydrogenation of hydrazine with a turnover frequency value of 24 h–1.
