- Abstract
Mesostructured CuMnCeO catalysts were prepared and tested in chlorobenzene destruction. Mn and Cu phases enter CeO matrix with a fluorite-like structure to form Cu-Mn-O-Ce solid solution. Both synthesis protocol and metal-doping content affect the metal state, reducibility, and oxygen distribution of composites. The ccc sample exhibits the highest activity with 90 % of chlorobenzene oxidized at around 250 °C. Enhanced oxygen concentration and mobility, and abundant oxygen vacancy promote the desorption of adsorbed Cl, which guarantees the superior stability of CuMnCeO. Incorporation of CuO and MnO effectively inhibits the formation of organic byproducts, such as phenolates, maleates, and o-benzoquinone, especially at elevated temperatures.
