Synthesis of nanorodperovskite catalysts and their catalytic performancesfor CO oxidation
The nanorod LaxK1-xCoO3 perovskite complex oxide catalysts were synthesized by sol-gel method using polyvinyl alcohol (PVA) as additive.These perovskite-type complex oxide catalysts were characterized by the techniques of XRD,IR,BET and SEM.And the results showed that nanorods of La1-xKxCoO3 perovskite-type complex oxides calcined at 700 ℃ for 4 h have been fabricated by sol-gel method when the mass concentration of PVA was 4%.The catalytic oxidation of CO showed that the LaxK1-xCoO3 catalysts had high activity.LaCoO3 nanorods exposed more ”110” plane than LaCoO3 nanoparticles,which is beneficial to CO catalytic oxidation.LaCoO3 nanorods had the best activity for the oxidation of CO.At 200 ℃,the CO conversion could reach 100%.
