Catalytic oxidation of toluene over Co-modified manganese oxide octahedral molecular sieves (OMS-2) synthesized by different methods
Abstract
Co/OMS-2 catalysts were prepared by different preparation methods, and their catalytic performance was investigated for the oxidation of toluene. The catalytic activity was revealed as sequence: OMS-2 > Co/OMS-2(one step method) >Co/OMS-2(impregnation method) > Co/OMS-2(ion exchange method), and the over performances of the different methodologies are quite similar to each other. It was found that OMS-2 achieved 90% toluene conversion at 225 °C. The decrease of catalytic performance over Co-containing catalysts originates from lower reducibility as well as the oxygen mobility on the surface of the Co/OMS-2 catalyst.
