Abstract

A metal-free azophenine-based catalyst has demonstrated exceptional efficiency in water reduction, requiring a 130 mV overpotential to achieve the benchmark current density. This catalyst retains its structural integrity and catalytic activity across diverse hydrolytic conditions. Its rapid reaction kinetics and efficient HER pathway were validated by combined experimental and theoretical investigations.
