Abstract

A cofacial iron porphyrin heterodimer, Fe₂ TPFPP-TMP showed high electrocatalytic activity, selectivity, and stability for O₂ reduction to H₂ O both in homogeneous non-aqueous and heterogeneous neutral aqueous solutions. When it is integrated to FTO/p-CuBi₂ O₄ (FTO=fluorine doped tin oxide) photocathode prepared by a simple novel method, a remarkable efficient solar-assisted O₂ reduction is achieved in neutral potassium phosphate (KPi) or basic NaOH solutions saturated with O₂ .
