| 1 | 富氢气氛中CO优先氧化CuO-CeO_2基催化剂的研究进展显示文摘CuO-CeO2基催化剂对富氢气氛中CO优先氧化具有优良的活性和选择性,是替代贵金属最具潜力的催化体系之一。本文系统总结了CO优先氧化用CuO-CeO2基催化剂的研究现状,着重阐述催化剂制备工艺、成分优化、助剂改性、载体调变等对催化性能的影响规律,介绍催化活性位与CO优先氧化的催化机理,探讨催化剂稳定性与失活机制等,同时指出该催化体系目前存在的主要问题,并展望了今后一段时期可能的发展趋势。 | 士丽敏 郑德山 王素敏 | 2011 | 化工进展2011，30，9： | 3 |
| 2 | CuO-CeO_2/Al_2O_3/FeCrAl monolithic catalysts prepared by in situ combustion synthesis method for preferential oxidation of carbon monoxide显示文摘This work described in situ combustion synthesis method for depositing CuO-CeO2 on the FeCrAl honeycomb supports.The in-fluence of the solution concentration and the role of the additive were studied and analyzed by scanning electron microscopy (SEM),X-ray diffractometer (XRD),and temperature programmed reduction (TPR) techniques.The results showed that 200 g/L of the active solution was the most appropriate concentration for preparing the monolithic catalysts,and the additives of praseodymium and lanthanum improved the adhesion stability of the monolithic catalysts.The addition of Pr did not greatly affect the catalytic performance,but CO could not be totally converted into CO2 after the addition of La into the CuO-CeO2/Al2O3/FeCrAl catalysts. | 曾尚红 苏海全 刘源 王岩 王东方 | 2011 | Journal of Rare Earths2011，29，1： | 3 |
