The as-synthesized Al-MCM-41 possessed hexagonal mesoporous silica with a<br \/>\nsurface area of 436 m2<br \/>\n\/g and a mesopore of 3.8 nm, allowing the incorporation of Ni and Ce into the Al-MCM-41<br \/>\nstructure. In a fixed-bed tubular reactor, the catalytic performance of the as-prepared catalyst was evaluated in<br \/>\nterms of CO2 conversion, CH4\/CO selectivity, CH4 yield, reaction rates per catalyst mass (rm), and catalyst surface<br \/>\n(rs), TOF, activation energy, and the deactivation rates of its corresponding activities at 250\u2013550 \u25e6C and 1 atm. As<br \/>\nthe Ce content increased, the catalytic activity greatly improved due to the improved Ni dispersion and higher<br \/>\nCO2 adsorption, although the porosity of the catalyst significantly decreased.
