Abstract A series of CrxFe2-xO3 mixed oxides were tested for catalytic combustion of dichloromethane. The best performance was obtained on a Cr0.8Fe1.2O3 catalyst (with a reaction rate of 3.11 mmol g−1 h−1 at 250 °C), which is higher than most of the results in literature. The reaction behavior was synergistically governed by the reducibility and surface acidity of the catalyst, which could be tuned by the compositions of Cr and Fe species in the mixed oxide. As a result, the Cr0.8Fe1.2O3 catalyst with an optimal combination of reducibility and surface acidity accounted for the best performance.
