NiO-LaCoO3催化剂的丙烷和CO氧化性能
Catalytic oxidation of carbon monoxide and propane on NiO-LaCoO3
摘要
Abstract
A series of NiO-LaCoO3were synthesized by solid-phase reaction method. The effects of calcination temperature and the content of Ni in catalyst on the carbon monoxide and propane oxidation performance of the as-synthesized catalysts were investigated. These catalysts were characterized by X-ray diffraction (XRD),hydrogen temperature-programmed reduction (H2-TPR) and other techniques. The results indicate that lower calcination temperature is beneficial for better catalytic performance. Among all catalysts,10NiO-LaCoO3calcinated at 700℃ exhibited the best catalytic performance. The addition of Ni into the structure of LaCoO3can significantly enhance the carbon monoxide and propane oxidation activity,and the optimal NiO loading is 7.5%. It was also found that the catalytic performance of catalysts is highly associated with oxygen mobility in catalysts.关键词
