Oxidation of alcohols using RuMnCe catalysts

The combination of ruthenium, manganese as well as cerium oxides formed an active catalytic system for the oxidation of 2-octanol and other alcohols. The addition of manganese species as promotors resulted in more active catalysts than comparable cobalt-doped oxidic materials. The application of RuMnCe oxides on redox-active supports, such as TiO2 or CeO2, by deposition–precipitation caused a further improvement of catalytic activity. A tolerance to nitrogen-containing substrates was observed.

The aerobic oxidation of 2-octanol and other alcohols to their corresponding ketones and aldehydes could successfully be achieved in the presence of Ru catalysts promoted with Mn and Ce oxides. The catalytic activity could significantly be improved by deposition of the ternary RuMnCe oxidic mixture on redox-active supports.Figure optionsDownload as PowerPoint slide
