文摘

We report a facile liquid impregnation approach for immobilization of ultrafine bimetallic Ni鈥揚t nanoparticles (NPs) inside the pores of MIL-101. The methods of powder X-ray diffraction, N₂ physisorption, X-ray photoelectron spectroscopy, transmission electron microscopy, and inductively coupled plasma-atomic emission spectroscopy were employed to characterize the NiPt@MIL-101 catalysts and further indicated the as-synthesized Ni鈥揚t NPs were confined in the pores of MIL-101. These as-synthesized bimetallic NiPt@MIL-101 NPs exhibit exceedingly high catalytic activity, selectivity, and durability toward hydrogen generation from alkaline solution of hydrazine.
