Abstract:	Oxygen reduction : A polarized water\|1,2‐dichloroethane (DCE) interface acts as a proton pump for the Co(tpp)] (TPP=5,10,15,20‐tetraphenylporphyrinato) catalyzed O₂ reduction by ferrocene (Fc) compounds to produce H₂O₂ (see figure; IT=ion transfer, ET=electron transfer). This system favours the collection of H₂O₂ by extraction immediately after its formation in DCE to the adjacent water phase.
