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

Nitrogen-doped porous carbons derived from ZIF-7 annealing at different temperatures have been synthesized and used as support matrices to anchor NiPt alloy and MnO_x NPs. The resulting (Ni₃Pt₇)_0.5–(MnO_x)_0.5/NPC-900 exhibits superior catalytic activity with TOF values of 706 and 120 h⁻¹ at 323 K and 298 K respectively, higher than most reported values.
