Characterization of TiO₂-Cordierite Carrier Prepared by APCVD and Sol-Gel Method

Abstract:

TiO2 has been loaded on cordierite porous ceramic to prepare the SCR catalyst carrier by using both APCVD and sol-gel method. The physical properties, SEM and SEM-EDX of the TiO2-cordierite carrier have been analyzed. The results showed that TiO2 loaded by APCVD method were of graininess shape and accumulated evenly. The loading rate of TiO2 and the specific area of carrier sample were increased 114% and 21% respectively when using APCVD method. In the results of sol-gel method, the maximal difference of Ti content was 66.92%, while the result of APCVD method was 18.89%. It demonstrated that TiO2 was uniformly attached with the cordierite ceramic by using APCVD method. That would ensure the active ingredients well loaded on the TiO2-cordierite carrier in the next process.
