The decomposition of water into O 2 and H ⊕ is an attractive process in many ways. The processes in a system consisting of ruthenium red (formula: [(NH 3 ) 5 Ru III ORu IV (NH 3 ) 4 ORu III (NH 3 ) 5 ]Cl 6 ) as catalyst. Ce IV as oxidizing agent, and, where necessary, Kaolin as carrier, can be explained as follows: Ce IV generates from ruthenium red a species that adds two H 2 O‐molecules to give 1 . Cleavage of H and formation of the OO bond leads to cyclic intermediates 2 , which decomposes into O 2 and ruthenium.
