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

Abstract

We report a new strategy for the design and construction of Co_xMn_yO_β for C₆H₆ oxidation, a representative VOC. The nanostructures of Co_xMn_yO_β can be tuned from nanowires to needles, hollow/hierarchical microspheres and nanocubes. Moreover, different nanostructures of Co_xMn_yO_β 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.
