摘要：A series of Ru/XCaCo-N catalysts with different Ca to Co3O4 mass ratios were synthesized using doping-etching strategy and the catalytic combustion performance of 1,2-dichloroethane (EDC) was investigated. Consequently, Ru/5CaCo-N-450 catalyst exhibited the excellent activity for the EDC elimination in different reaction conditions, as well as stability against high temperature. The characteristic results revealed that the existing of abundant oxygen vacancies in Ru/5CaCo-N-450 catalyst significantly improved the redox and acidity property and enhanced the high-temperature sintering stability through the interaction of Ru species with Co3O4. The results of in-situ DRIFTS spectra indicated the promoted contribution of oxygen vacancies that facilitated the adsorption and activation of EDC, and synergistic effect between Ru species and Co3O4 benefited to the elimination of absorbed Cl species as well as the ability of deep oxidation for intermediates. Thus, an excellent catalyst with high activity and stability has been investigated in detail using a doping-etching strategy, and the relatively simple and environmentally friendly synthesis method provides a broad prospect for potential industrial applications.
