A series of cordierite monolithic catalysts with Ru species supported on different available low-cost carriers were prepared and investigated for the elimination of CVOCs. The results suggest that the monolithic catalyst with Ru species supported on anatase TiO 2 carrier with abundant acidic sites exhibited the desired catalytic activity for DCM oxidation with the T 90% value of 368 °C. In addition, a pseudo-boehmite sol used as binder was introduced into the preparation of the monolithic catalysts to further improve the adhesion between the powder catalysts and cordierite honeycomb carrier. The results suggest that although the T 50% and T 90% of the Ru/TiO 2 /PB/Cor shifted to higher temperature of 376 and 428 °C, the weight loss of the coating for the Ru/TiO 2 /PB/Cor catalyst was improved and decreased to 6.5 wt%. Also, the as-obtained Ru/TiO 2 /PB/Cor catalyst exhibited ideal catalytic properties for the abatement of ethyl acetate and ethanol, indicating that the catalyst can meet the demand for the treatment of actual multi-component industrial gas.
