Abstract

The M-OMS-2(M = Cu2+, Co2+, Cr3+, H+, Ag+) catalysts have been synthetized by reflux method following with ion exchange or co-precipitation procedures. Characterisation of these materials by XRD, TGA, SEM and BET surface were fulfilled. Studying of their catalytic activities in the oxidation of carbon monoxide shows the capacity of the OMSs at rather low temperature (80-170oC) in order: Ag-OMS-2> Cr-OMS-2 > Cu-OMS-2 > Co-OMS-2 >H-OMS-2 > OMS-2
