摘要
本文采用溶胶-凝胶法在不同温度下制备了纳米级的类钙钛矿型复合氧化物La2NiO4。采用XRD、TPR、SEM和TG-DTA等实验技术对催化剂进行了表征,并且考察了该催化剂对CH4/CO2重整反应的催化活性。实验结果表明高于850℃焙烧制备的La2NiO4催化剂,其催化活性、稳定性及抗积炭性能较好。
The nano-sized La2NiO4 perovskite-like oxides were prepared by Sol-gel technology in different calcination temperature.The characters of the samples were analyzed by XRD,TPR,SEM and TG-DTA.At the same time,their catalytic activitives for carbon dioxide reforming of methane were also tested.The results showed that the sample prepared in 850 ℃ showed better catalytic activity,stability and ability to accumulate carbon.
