Abstract

Hybrid electrocatalyst of ultrafine Pt particles anchored on a Ni3[Fe(CN)6]2 nanocube with low Pt loading of 4.0% is designed for HERs, and superior catalytic activity is obtained in both acidic and alkaline media because the Ni species remarkably facilitates the reaction kinetics of water dissociation and thus improves HER activity.
