Abstract

Herein, hydrated copper pyrophosphate ultrathin nanosheets with a unique “pit-dot” nanostructure were fabricated as efficient pre-catalysts for the oxygen evolution reaction, and systematic post-catalytic characterization studies confirmed the important role of the boosted pre-oxidation reaction in promoting the OER catalysis.
