Oxidation of ethanol over Mn–Ce–O and Mn–Ce–Zr–O complex compounds synthesized by sol–gel method

Removal of fluoride by hydrous manganese oxide-coated alumina: Performance and mechanism

“…Binding energy of Mn 2p3 was usually used to identify the valence of manganese. The component at 642.46 eV can be attributed to Mn 4+ [33]. After exposed to NaF, these Mn peaks moved to a higher energy side (643.17 eV, Mn 4+ still).…”

Synthesis of Highly Effective CeO x –MnO y –BaO Catalysts for Direct NO Decomposition

“…Among the numerous ceria-based catalysts, MnO x -CeO 2 catalysts have been found to be remarkably active for wet oxidation of phenol [2], SCR of NO with NH 3 [3], and catalytic NO x sorption [4] as well as oxidation of ethanol [5], formaldehyde [6], toluene [7], o-xylene [8], and VOC [9]. The MnO x -CeO 2 solid solutions have been prepared by various methods, i.e., co-precipitation [2-4, 6, 8, 10], citric acid sol-gel [5][6][7]10], wet-impregnation [10], and solution combustion [9,11] methods. For example, Chen et al [2] prepared Mn-Ce-O composites with various atomic ratios by co-precipitation methods and showed on the basis of X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) results that Mn ions are incorporated in the fluorite structure of ceria.…”

Ce–Zr–Sr ternary mixed oxides structural characteristics and oxygen storage capacity

“…In present work, amount of DOSC is calculated based on the CO 2 produced, which is integrating the area under CO 2 peak during one integral CO-O 2 cycle in form of mol [O] g −1 . DOSC is calculated by the follow equations [25,26]:…”
