Abstract

Nanoporous materials: High-aspect-ratio, ordered porous Co 3O4 layers were formed by self-organizing anodization of a cobalt substrate and subsequent annealing. The key for successful formation of such layers is to sufficiently suppress competing oxygen evolution during anodization. The aligned Co3O4 channel layers behave as a highly efficient water oxidation catalyst (see picture). Copyright 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
