Abstract

In this paper, Co_xMn_1−xCeO_δ mixed oxides were synthesized using a co-precipitation method. The catalyst's performance for the benzene combustion reaction was evaluated, and Co_0.25Mn_0.75CeO_δ (CMC-0.25) exhibited good catalytic activity, stability and CO₂ selectivity. The prepared catalysts were characterized and analyzed completely by XRD, BET, Raman, TEM and HRTEM, XPS, H₂-TPR, and O₂-TPD. The results demonstrated that a solid solution was formed with more active oxygen induced by Co doping. Strong interaction effects among Co-Mn-Ce-O were speculated as the main mechanisms underlying the high-efficiency catalytic capacity. The prepared Co-doped Mn-Ce mixed oxides catalyst may be a potential low-cost catalyst alternative to replace industrial noble metal catalysts.
