英文摘要	In this study, we constructed multi-dimensional CoFeOx catalysts for the catalytic oxidation elimination of o-dichlorobenzene (o-DCB). The dimension of the catalyst was modulated to promote the dispersion of components and thus improve the surface active oxygen species. The effects of the multi-dimensional CoFeOx catalysts on surface active oxygen species and the o-DCB elimination performance were investigated. The temperatures of o-DCB catalytic oxidation with 90% conversion (T-90) over the 2D/1D CoOx/CoFeOx, 2D CoFeOx and 2D/1D CoFeOx/CoOx catalysts were 395, 405, and 365 degrees C, respectively. The results showed that the oxygen vacancies of the 2D/1D CoFeOx/CoOx catalysts were enhanced due to the multi-dimensional effect compared to 2D CoFeOx. The outstanding catalytic activity and thermal stability of 2D/1D CoFeOx/CoOx were mainly attributed to its large specific surface area, pore volume and pore size, more Co3+ content, excellent reducibility, large number of surface adsorbed oxygen (O-sur) species and rich oxygen vacancies.
