|Title:||Role of potassium in the aerobic oxidation of aromatic alcohols over K+-promoted Mn/C catalysts||Authors:||Tang, Q.
|Issue Date:||20-Sep-2008||Citation:||Tang, Q., Liu, T., Yang, Y. (2008-09-20). Role of potassium in the aerobic oxidation of aromatic alcohols over K+-promoted Mn/C catalysts. Catalysis Communications 9 (15) : 2570-2573. ScholarBank@NUS Repository. https://doi.org/10.1016/j.catcom.2008.07.013||Abstract:||The aerobic oxidation of aromatic alcohol on alkali metal promoted Mn/C catalysts has been investigated. A dramatic improvement of the oxidation activity can be observed when the Mn/C catalyst is modified with potassium ions. Characterizations of Raman and X-ray absorption fine structure (XAFS) evidence that potassium ions induce a large local distortion to Mn-O octahedrons in supported manganese oxides with coexistence of Mn2+ and Mn3+, which has been suggested to be a vital factor to enhance the activation of O2 for the oxidation of benzylic alcohol. © 2008 Elsevier B.V.
