The role of Ce addition in catalytic activity enhancement of TiO₂-supported Ni for CO₂ methanation reaction.

ABSTRACT: In this work, various amounts of Ce were added to TiO₂ to form a mixed oxide support; Ce _x Ti_1-x O₂ (x = 0, 0.003, 0.05, 0.10 and 0.15) and then those synthesized supports were impregnated by 10 wt% Ni to produce a catalysts. The 10 wt% Ni-Ce _x Ti_1-x O₂ (x = 0, 0.003, 0.05, 0.10 and 0.15) catalysts were tested for CO₂ methanation reaction by using a fixed-bed reactor in the temperature range of 100-500 °C. The sample was pretreated at 450 °C under H₂ and then a mixed feed gas of CO₂ and H₂ was switched into the reactor to start the reaction. The results showed that 10 wt% Ni-Ce_0.003Ti_0.997O₂ catal
