Abstract

The design of a protective electron-rich surface is an ideal route to enhance the performance of catalysts. Due to the higher work function of Ni₃B, facile-directed electron transport occurs from PtNi to Ni₃B to enrich electron density on the surface of the Ni₃B shell. This process increases hydrogen adsorption–desorption kinetics and mitigates Cl⁻ corrosion.
