While our results suggest the polymers in this study do not function as electrocatalysts for the initial reduction of oxygen to superoxide (i.e. through an adsorption-driven inner-sphere process), they suggest there may be opportunities for polymers to serve as catalysts for the disproportionation of superoxide into O2 and HxO2 . Additionally, the lack of metal centers that would likely drive intermediate adsorption and operation through the outer-sphere pathway enables p(NDI-T2 P75) to highly selective for H2O2 production at low overpotentials when operating in high pH, suggesting promising opportunities for this emerging class of polymer electrodes.
