摘要
Highly dispersed Ni-based catalysts for CO2 methanation have been extensively studied over the last decade. However, a highly loaded Ni-based catalyst always results in a large Ni particle size and poor CO2 methanation activity. In this work, a colloidal solution combustion method was used to prepare a highly loaded Ni-La2O3 catalyst (50 wt % Ni) with a small Ni particle size and abundant metal-support interface. The characterizations demonstrated that a Ni-La2O3 catalyst prepared in this way has a mesoporous structure and a small Ni particle size. Due to the small Ni particle size and abundant metal-support interface, the highly loaded mesoporous Ni-La2O3 catalyst exhibits higher activity and selectivity in CO2 methanation compared to the Ni-La2O3 catalyst prepared by a conventional solution combustion method.
