| 摘 要： | 以硝酸锰为前躯物,采用传统浸溃法合成了一系列不同锰含量的Mn/MgO催化剂.通过X射线衍射(XRD),N2物理吸附、Raman光谱、X射线吸收光谱(XAS)及程序升温还原(H2-TPR)对负载锰氧化物的分散度、氧化态、配位环境进行了表征.结果发现,Mn负载量是控制负载锰氧化物分散度和配位环境的重要因素.当Mn负载量小于...

| Abstract: | A series of Mn/MgO catalysts with different Mn loadings are prepared by a conventional wet impregnation method using manganese nitrate as the precursor.The dispersion,oxidation state,and local coordination of supported manganese oxides are characterized by X-ray diffraction,Raman,X-ray absorption,and hydrogen temperature-programmed reduction(H2-TPR).Manganese loading is found to be a vital factor in controlling the dispersion and local environment of supported manganese oxides.Highly dispersed manganese oxi... |
