In this work, a novel Ni/AlO-P catalyst for CO methanation was prepared via an oxygen plasma decomposition of the Ni-MOF@AlO core–shell precursor. The obtained catalyst showed a higher Ni dispersion (26.5%) and contained less NiAlO spinel when compared with the Ni/AlO prepared by the traditional method. The Ni/AlO-P catalyst showed significantly enhanced efficiency toward CO methanation as compared with those catalysts with a similar nickel loading but are prepared using the traditional method. For example, the space time yield of methane (STY) of the Ni/AlO-P catalyst was as high as 21103.6 mg∙g∙h at 400 °C and GHSV as 12000 ml∙g∙h, which is 3.4 times higher than that of the reported catalyst (6190.5 mg∙g∙h) with a similar nickel loading under similar reaction conditions. Moreover, Density Functional Theory (DFT) studies together with the CO-TPD results revealed that both nickel surface and Ni-AlO interface could activate CO, while the NiAlO surface could not.
