Ni-Al mixed metal oxide with rich oxygen vacancies:CO methanation performance and density functional theory study
文献摘要：
Ni-Al mixed metal oxides have been successfully prepared by high shear mixer(HSM)and coprecipita-tion(CP)methods for low temperature CO methanation.In this work,Ni-Al(HSM-CP)catalyst presented small Ni crystallite size and high surface area,which all contribute to the methanation reaction at low temperature conditions.The obtained Ni-Al(HSM-CP)sample exhibited a mass of defective oxygen,thereby accelerating the dissociation of CO and ultimately increasing the activity of the catalyst.Ni-Al(HSM-CP)catalyst offered the best activity with CO conversion=100％and CH4 selectivity=93％at 300℃,and the CH4 selectivity can reach 81.8％at 200℃.In situ Fourier transform infrared spectroscopy and density functional theory show that CHO and COH intermediates with lower activation energy bar-riers are produced during the reaction,and hydrogen-assisted carbon-oxygen bond scission is more favorable.
