摘要：

Light, inexpensive, effective: Nanostructured Co3O4 clusters (see picture) in mesoporous silica are the first example of a nanometer-sized multielectron catalyst made of a first-row transitionmetal oxide that evolves oxygen from water efficiently. The nanorod bundle structure of the catalyst results in a very large surface area, an important factor contributing to the high turnover frequency. © 2009 Wiley-VCH Verlag GmbH & Co. KGaA.
