Electrocatalytic Hydrogen Production by an Aluminum(III) Complex: Ligand-Based Proton and Electron Transfer

摘要

Environmentally sustainable hydrogen-evolving electrocatalysts are key in a renewable fuel economy, and ligand-based proton and electron transfer could circumvent the need for precious metal ions in electrocatalytic H-2 production. Herein, we show that electrocatalytic generation of H-2 by a redox-active ligand complex of Al3+ occurs at -1.16 V vs. SCE (500 mV overpotential).
