Abstract In order to develop a loading method with more general application range and stronger loading strength, Si—O—Si bond was formed between the silicon alcohol formed by hydrolysis of silane coupling agent and the substrate surface of the material, and the coating layer was grafted on the fiber surface, so that the catalyst and filter material could be firmly combined. Its structure and properties were studied by scanning electron microscopy (SEM), X-ray diffraction (XRD), infrared (FTIR) and CO-SCR activity evaluation. It could be seen from SEM photos that the catalyst was evenly dispersed on the filter material. The XRD spectrum of the composite filter material showed that the polymetallic composite oxide was loaded on the filter material in an amorphous state. In addition, the conversion of NO_x of the composite filter material was 90%, when the mass ratio reached 0.25. The composite filter material had good NO_x removal effect in the range of 200~260 ℃. Furthermore, during the continuous 10 h stability test, the catalytic efficiency of the composite filter material did not decrease significantly, showing great resistance of catalytic performance.
