A series of CuCoOx catalysts supported on TiO2 were prepared by impregnation for catalytic CO oxidation. The results of XRD and TPR analysis and BET testing showed that the catalyst calcined at 350℃ has a spinel structure of CuCo2O4 having a larger specific surface area and a better catalytic efficiency. At 110℃, CO with 1% concentration can be completely oxidized into CO2. Effects of calcination temperature, reaction temperature, CO concentration, space velocity as well as the influence of SO2 and H2O on CO conversion have been investigated. The prepared catalyst has good poison resistance against SO2 and H2O, which can be used for removing CO from flue gas that contains either SO2 or H2O.
