Light, inexpensive, effective : Nanostructured Co 3 O 4 clusters (see picture) in mesoporous silica are the first example of a nanometer‐sized multielectron catalyst made of a first‐row transition‐metal 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.
