Gram-scale synthesis of small-sized PtM intermetallics as high-performance catalysts for the hydrogen evolution reaction

Pt-based intermetallics exhibit excellent activity in electrocatalysis. However, their controlled syntheses remain difficult. Herein, carbon-supported PtM (M = Fe, Co, Ni, Zn and Mn) intermetallics with small size (3 nm) were prepared at the gramscale and applied as a highly effective electrocatalyst for the hydrogen evolution reaction. Carbon-supported PtM (M = Fe, Co, Ni, Mn, etc.) intermetallics with small size (approximate to 3 nm) were prepared at the gram scale and applied as a highly effective electrocatalyst for the hydrogen evolution reaction.
