oxidation potential

I've seen the table of oxidation potentials: ClO2=0.95V, O2=1.3V, H2O2=1.8V, O3=2.07V.

Can I reduce the oxidation potential of hydrogen peroxide by 50% to get the same biological effect as chlorine dioxide? Would it be safer, better-tasting, or cheaper? I'm not exactly sure how such a thing would be done but a google suggests KI has something to do with it.

In all honesty I want to rule out the possibility that the whole chlorine dioxide thing is just a profit-making gimmick, i.e. H2O2 is super cheap.
