Ruthenium dioxide hydrate, is it a redox catalyst?
Abstract
Ruthenium dioxide hydrate is shown to be a poor redox catalyst for O2 evolution from Ce4+, unless it is bound to an inert support such as titanium dioxide; this is attributed to the release of RuO4 into the gas phase which was observed when ruthenium dioxide hydrate alone was used but not when it was bound to titanium dioxide.
