    摘要:Core-shell type Co0.24 Ba (CS) catalyst was prepared by adsorption-deposition method, in which cobalt oxide with small amount of Ba incorporation mainly exists in the porous shell over the BaCO3 support core. This structure of the catalyst not only endues the active component Co a high accessibility to the reactant, but also made the active component promoted by barium better. Due the special structure, the catalyst is much more active in N2O decomposition compared with the catalysts with traditional structure. Over the Co-0.24 Ba (CS) catalyst that containing only 8.91 wt.% of Co3O4, N2O in feed gas 2000 ppmv N2O/Ar with 20,000 h(-1) was 100% decomposed at 400 degrees C.
