Abstract

Ozone is found to promote the monochlorobenzene (CB) catalytic oxidation over carbon nanotubes supported copper oxide composite up to reaction temperature of 300 C. Especially at 250 C, a CB conversion of 99 %, together with a CO₂ selectivity of 98 %, was observed. The selective adsorption of CB, the promotion of Cu⁺ to Cu²⁺ oxidation, and the combination of O₃ and high temperature activated gas phase O₂ are all considered to attribute to the high CB conversion and CO₂ selectivity at temperature above 250 C. Graphical Abstract: Effects of O₃ on catalytic oxidation of CB over CuO_X/CNTs were studied. A CB conversion of 99 % and a CO₂ selectivity of 98 % were achieved at 250 C, which could be mainly attributed to the synergy between the CB oxidation by O₃ and activated O₂.
