O3
H2O2 cannot oxidise O3, as ozone (O3) is a powerful oxidising agent. The reasons is that ozone has higher energy content than dioxygen and hence decompose to give dioxygen and atomic hydrogen.
O3(g) → O2(g)(Dioxygen) + O(g) (atomic oxygen)
H2O2 on reaction with O3 shows the following reaction
H2O2 + O3 → H2O + 2O2
i.e both reduce each other.
However, H2O2 oxidise PbO → PbSO4
Na2SO3 → Na2SO4
KI → K2SO4
