NiPt–MnOx supported on N-doped porous carbon derived from metal–organic frameworks for highly efficient hydrogen generation from hydrazine

Abstract

Safe and efficient storage of hydrogen is the key issue for the hydrogen economy. Hydrazine monohydrate is regarded as a potential hydrogen carrier. Herein, we report a facile synthesis of NiPt–MnOx supported on nitrogen-doped porous carbon (NPC) derived from annealing metal–organic frameworks (MOFs) at different temperatures in Ar. Interestingly, the obtained (Ni3Pt7)0.5–(MnOx)0.5/NPC-900 exhibits superior catalytic activity toward dehydrogenation of an alkaline solution of hydrazine, with initial turnover frequency values of 706 and 120 h−1 at 323 K and room temperature, respectively. This excellent catalytic performance may have resulted from the synergistic electronic effect of NiPt and MnOx, the small size and high dispersion of NiPt–MnOx nanocatalysts, NPC as an excellent support with large pore volume, high surface area, high nitrogen content, electrical conductance, and also the high density of the metal-N active sites between NiPt–MnOx and NPC.
