The processes in a system consisting of ruthenium red (formula: [(NH3)5RuIIIORuIV(NH3)4ORuIII(NH3)5]Cl6) as catalyst. CeIV as oxidizing agent, and, where necessary, Kaolin as carrier, can be explained as follows: CeIV generates from ruthenium red a species that adds two H2O-molecules to give 1. Cleavage of H and formation of the OO bond leads to cyclic intermediates 2, which decomposes into O2 and ruthenium. References 1 M.
