Hydrogen Evolution from Water under Aerobic Conditions Catalyzed by a Cobalt ATCUN Metallopeptide

The cobalt complex of an amino-terminal copper and nickel (ATCUN) motif model tripeptide (CoGGH) is shown to act as an electrocatalyst for hydrogen evolution from water near neutral pH with high Faradaic efficiency. The catalyst performance is not significantly impacted by exposure to oxygen. CoGGH...

Zusammenfassung:The cobalt complex of an amino-terminal copper and nickel (ATCUN) motif model tripeptide (CoGGH) is shown to act as an electrocatalyst for hydrogen evolution from water near neutral pH with high Faradaic efficiency. The catalyst performance is not significantly impacted by exposure to oxygen. CoGGH represents a new class of hydrogen evolution catalyst that is straightforward to prepare and to modify.
