The Y was used for improving the structural performance of TiO2support. The results showed that the BET surface area was increased by doping Y, and more oxygen vacancies were generated in the TiO2support, which would promote the activation of CO2. The reduction temperature of the Co3O4was decreased and more Co3O4can be reduced into Co for the Y doped Co/TiO2samples compared to that of the Co/TiO2. Furthermore, the doped Y enhanced the basicity of the catalysts and the adsorption capacity of the CO2was greatly increased, which was beneficial to the activation of the CO2and the CO2methanation reaction. The activity test indicated that the CO2conversion and CH4selectivity was highest when using the 20% Co/2%Y-TiO2catalyst. The 20% Co/2%Y-TiO2catalyst exhibited the highest CO2conversion of 85.9%, and CH4selectivity of 99.5% at 350 °C, and kept stable in 40 h.
