Abstract

Shapes of catalysts to come Tricobalt tetraoxide (Co3O4) has been much investigated as a potential catalyst for the low-temperature oxidation of carbon monoxide, useful for example in automotive emission control. Although this material is active even at sub-zero temperatures, it is highly sensitive to even trace amounts of moisture. Xiaowei Xie et al. now establish that Co3O4 in the form of nanorods shows higher catalytic activity, and enhanced stability in the presence of water; they attribute these improvements to the high density of catalytically active Co3+ sites exposed on the nanorod surface. Health risks associated with cobalt use mean that this specific material might not found widespread application for air purification, but these findings demonstrate the potential for morphological control for improving the performance of transition metal oxide catalysts.
