I am wondering is it possible to use controlled amounts of iron(III) oxide with salt perchlorate by heating to form iron chloride and O2. Similarly, would this reaction work with perchloric acid instead, giving off oxygen and water?
This reaction seems to work on paper since Cl is a much better oxidizer but can find no clear answer.
FeO2 + 2ClO4(s) --> FeCl2 + 6O2
FeO2 +2HClO4(aq) --> FeCl2 + H2O + 4O2 + O^-1
