Nickel–platinum nanoparticles immobilized on graphitic carbon nitride as highly efficient catalyst for hydrogen release from hydrous hydrazine

Abstract

Here we demonstrate that the combination of NiPt alloy nanoparticles with a graphitic carbon nitride (g-C₃N₄) support facilitates H₂ production from hydrous hydrazine in an alkaline solution under moderate conditions. Of all the heterogeneous catalysts tested, Ni₃₇Pt₆₃/g-C₃N₄ shows superior catalytic performance with a maximum initial turnover frequency (TOF) of 570 h⁻¹ at 323 K.
