Honeycomb CO oxidation catalyst carrier material and preparation method thereof

The invention relates to the technical field of carbon monoxide catalytic oxidation, in particular to a honeycomb-shaped CO oxidation catalyst carrier material and a preparation method thereof. Comprising a honeycomb-shaped metal oxide composite carrier and a palladium metal coating loaded on the surface of the honeycomb-shaped metal oxide composite carrier, the honeycomb metal oxide composite carrier is prepared from the following components in percentage by mass: 80 to 85 percent of TiO2, 3 to 6 percent of WO3, 0.3 to 0.5 percent of V2O5 and the balance of Al2O3 and SiO2. The catalyst carrier material takes transition metal and noble metal palladium as catalytic components; the catalyst has the characteristics of high oxidation efficiency, high air speed and low action temperature; the catalyst also has the advantages of high catalytic activity, high CO oxidation efficiency, extremely low catalyst activity attenuation rate and stable performance; the device is suitable for high-humidity flue gas conditions
