AbstractThe electrolysis of water provides a link between electrical energy and hydrogen, a high energy density fuel and a versatile energy carrier, but the process is very expensive. Indeed, the main challenge is to reduce energy consumption for large-scale applications using efficient renewable catalysts, which can be produced at low cost. Inspired by the water oxidation process catalyzed by inorganic Cu-complexes, we present the multicopper oxidase laccase as the first ever enzyme reported able to catalyze electrooxidation of H2O to molecular oxygen. Native and laboratory evolved laccases immobilized onto low-density graphite electrodes serve as bioelectrocatalytic systems with low overpotential and a high O2 evolution ratio against H2O2 production during H2O electrolysis. Our results open a new research ground on H2O splitting as they allow overcoming serious practical limitations associated with artificial electrocatalysts used for O2 evolution nowadays.
