Abstract

Abstract: Herein, ternary metal phosphides NiCoP nanoparticles supported on porous hexagonal boron nitride (h-BN) was fabricated via hydrothermal-phosphorization strategy. The as-prepared Ni0.8 Co1.2 P@h-BN exhibited excellent catalytic performance for the hydrogen generation from ammonia borane (AB) hydrolysis, with an initial turnover frequency of 86.5 mol(H2 ) mol(Ni0.8 Co1.2 P) −1 min −1 at 298 K. The experimental outcome can be attributed to the synergistic effect between Ni, Co and P, as well as the strong metal-support interaction between NiCoP and h-BN. This study presents a new paradigm for supporting transition metal phosphides, and provides a new avenue to develop high performance and low cost non noble metal catalysts for hydrolysis of AB. Highlights: NiCoP nanoparticles supported on porous hexagonal boron nitride was fabricated. The Ni0.8 Co1.2 P@h-BN exhibits high activity for dehydrogenation of ammonia borane. The TOF value of the catalyst is 86.5 mol(H2 ) mol(Ni0.8 Co1.2 P) −1 min −1 at 298 K.
