| Abstract | The layered copper manganese oxide (LCMO) with a bridged monoclinic/tetragonal phase structure was successfully prepared by one-step hydrothermal redox-precipitation method and demonstrated highly efficient and stable catalytic capability to CO and VOCs oxidation. The formation of monoclinic-tetragonal phase interface with abundant defects inhibited the growth of nanoparticles which was benefit to keep smaller crystal size and higher surface area. Characterization results indicated that the interfacial structure of mixed phases can induce the formation of the Cu2+-O2--Mn4+ entity, which led to abundant of surface oxygen species and oxygen vacancies, as well as improved low-temperature reducibility, which played key roles in catalytic activity. The T-50 and T-90 in the CO and VOCs oxidation decreased remarkably with the increase of the surface oxygen species and oxygen vacancies content. Furthermore, the LCMO showed an excellent resistance to H2O, SO2, CO2 and other VOCs, which demonstrated the catalyst had great potential for practical application. |
