Molecular electrocatalysis for oxygen reduction at a polarized water/1,2-dichloroethane (DCE) interface was studied, involving aqueous protons, ferrocene (Fc) in DCE and amphiphilic cobalt porphyrin catalysts adsorbed at the interface. The catalyst, (2,8,13,17-tetraethyl-3,7,12,18-tetramethyl-5-p- amino-phenylporphyrin) cobalt(II) (CoAP), functions like conventional cobalt porphyrins, activating O2 via coordination by the formation of a superoxide structure. Furthermore, due to the hydrophilic nature of the aminophenyl group, CoAP has a strong affinity for the water/DCE interface as evidenced by lipophilicity mapping calculations and surface tension measurements, facilitating the protonation of the CoAP-O2 complex and its reduction by ferrocene. The reaction is electrocatalytic as its rate depends on the applied Galvani potential difference between the two phases. © 2010 American Chemical Society.

Cobalt fluoro-phthalocyanine (CoFPc) can efficiently catalyze the reduction of oxygen (O2) by a weak electron donor, namely tetrathiafulvalene (TTF), at the polarized water/1,2-dichloroethane (DCE) interface. Two-phase shake flask experiments and ion transfer voltammetry results suggest that the catalytic reaction proceeds as a proton-coupled electron transfer reduction of oxygen to mainly hydrogen peroxide, where a proton transfer from water to DCE is occurring concomitantly with the electron transfer reaction between TTF and oxygen. © 2012 Elsevier Ltd.
