OMS-2 supports were synthesized by three different methods,and a series of CuO/OMS-2 catalysts with CuO loading of 10.0 t%(mass fraction)were synthesized by the impregnation method.The synthesized catalysts were characterized by X-ray diffraction,N_2 adsorption,transmission electron microscopy,X-ray photoelectron spectroscopy and H2-temperature programmed reduction and their catalytic activities for CO oxidation were evaluated on a continuous flow fixed-bed reactor.It was found that the S-OMS-2 synthesized ...
