Crystalline mesoporous materials as catalysts have attracted attention in recent years, but their application in catalytic reduction of N2O has not been reported yet. In this work, a series of mesoporous transition metal oxides (CeO2, Co3O4, Cr2O3, CuO, α-Fe2O3, β-MnO2, Mn2O3, Mn3O4, NiO) with ordered nanopores and crystalline walls, synthesized by a hard-templating method, were tested in the catalytic reduction of N2O by CO. All of them exhibited significant catalytic activities above 300 °C. In particular, m-Co3O4, m-CuO, and m-Fe2O3 showed 100% N2O conversion at 250 °C. Besides, m-CuO was obviously activated during the recyclability test. The fresh and spent catalysts were characterized to probe potential structural and compositional changes.
