An iron-based molecular cathode for alkaline electrocatalytic hydrogen evolution

Abstract

Herein, we investigate the heterogenization of a molecular iron complex containing a p-chloropyridine moiety through simple electroanalytical techniques and explore its electrocatalytic HER efficacy. The modified electrodes are active in alkaline aqueous solutions, have low overpotentials (0.35 V vs. RHE) and showed stability for over 150 hours under electrolysis conditions.
