Ni–Pt nanoparticles supported on MIL-101 as highly efficient catalysts for hydrogen generation from aqueous alkaline solution of hydrazine for chemical hydrogen storage

Highly dispersed bimetallic Ni–Pt nanoparticles with different compositions supported on MIL-101 have been successfully synthesized by a simple liquid impregnation method. The as-synthesized NPs in an average of 1.9 ± 0.4 nm could be isolated by certification and characterized by using PXRD, TEM, EDX, XPS, BET, and ICP-AES. Catalytic activity of the Ni–Pt@MIL-101 was tested in the hydrogen generation from aqueous alkaline solution of hydrazine. These catalysts were composition dependent for the catalytic activity. Among all the Ni–Pt@MIL-101 catalysts tested, the Ni88Pt12@MIL-101 exhibited the highest catalytic activity, with the turnover frequency (TOF) value of 350  mol H 2 mol metal − 1 h − 1 at 50 °C, which is the highest among all the previously reported catalysts.
