The Ni/CeO2 catalysts are prepared by different methods. Accordingly, the Ni/CeO2-C catalyst synthesized a simple precipitation and impregnation method was developed to obtain an excellent low-temperature activity for CO2 methanation. conversion reached 81.2%, achieved CH4 selectivity as high 100% even at temperature low 250 °C under gas hourly space velocity of 30,000 mL/(g·h) over Ni/CeO2-C. After 50 h stability test, performance still maintained 87.5% 100%. characterization results show that dispersion, particle size, reducibility Ni nanoparticles on Ni/CeO2-P same, which indicates physical structure is similar, difference in mainly caused chemical properties. Compared pure CeO2, exhibits significantly increased amount oxygen vacancies. According basic site there higher density sites than Ni/CeO2-P. Basic can also adsorb activate molecules, conducive further reaction. presence OH groups crucial they influence rate methanation through adsorption, activation, well their effects H*.
