Facile fabrication of shape-controlled CoxMnyOβ nanocatalysts for benzene oxidation at low temperatures.

We report a new strategy for the design and construction of CoxMnyOβ for C6H6 oxidation, a representative VOC. The nanostructures of CoxMnyOβ can be tuned from nanowires to needles, hollow/hierarchical microspheres and nanocubes. Moreover, different nanostructures of CoxMnyOβ show diverse textural/structural/surface properties, which in turn show strikingly different catalytic performances. Benefitting from its unique structural feature, nanocubic MnO2 exhibits a superior to considerably high activity for C6H6 oxidation at low temperatures.
