Preparation, characterization and catalytic behavior of hierachically porous CuO/α-Fe2O3/SiO2 composite material for CO and o-DCB oxidation

Hierachically porous (HP) CuO/α-Fe2O3/SiC2 composite material was fabricated by sol-gel method and multi-hydrothermal processes using HP-S1O2 as support. The resulting material was characterized by N2 adsorption-desorption, X-ray diffraction and scanning electron microscopy. The as-prepared CuO/Fe2O3/HP-SiC2 sample, with α-Fe2CO3 and CuO nanocrystals, possessed a co-continuous skeleton, through-macroporous and mesoporous structure. Its catalytic behavior for CO and o-DCB oxidation was investigated. The result showed that CuO/Fe2O3/HP-SiCO2 catalyst exhibited high catalytic activity for both CO and o-DCB oxidation, indicating its potential application in combined abatement of CO and chlorinated volatile organic compounds.
