Catalysis of hydrogen evolution reaction by Ni12P5 single crystalline nanoplates and spherical nanoparticles

Abstract

Elaborate design of highly active catalysts from earth-abundant elements is important to the water-splitting devices. We have synthesized {-2 1 1} high index faceted Ni12P5 nanoplates and Ni12P5 spherical nanoparticles (SNPs) by a one-step solventhermal method. The Ni12P5 nanoplates show enhanced hydrogen evolution reaction activity with a lower overpotential of -128 mV and a smaller Tafel slope of 60.6 mV/dec, compared to the Ni12P5 SNPs. Stability tests reveal the exceptional durability of the catalyst. This work offers an attractive catalytic material for large-scale hydrogen production technology.
