Abstract:
An etching-intralayered Ostwald ripening process is proposed, which leads to the formation of a β-Ni(OH)2 ultrathin nanomesh with abundant and uniformly distributed nanopores of 3-4 nm. The nanomesh catalyst exhibits outstanding oxygen evolution reaction performance, with high catalytic current density and superior long-term stability, making this Earth-abundant nanomesh catalyst a promising candidate for commercial water splitting.
