Abstract

Ni-CeO₂/SBA-15-V catalyst was prepared by the impregnation method with vacuum thermal treatment and used for CO₂ methanation reaction. Compared with Ni-CeO₂/SBA-15-air catalyst with thermal treatment in air, the reduced Ni-CeO₂/SBA-15-V catalyst with vacuum thermal treatment exhibited higher Ni dispersion and smaller Ni particle size. In CO₂ methanation reaction, the Ni-CeO₂/SBA-15-V catalyst was more active and selective than the Ni-CeO₂/SBA-15-air catalyst. The good activity and selectivity of Ni-CeO₂/SBA-15-V catalyst should be due to highly dispersed Ni in contact with small CeO₂ particles.
