NJCRSC Esi

This document discusses iron oxide decorated N-doped carbon derived from Poly (ferrocene-urethane) interconnects for oxygen reduction reaction. It includes supporting information such as steady state LSV responses of RRDE at different rotation rates, number of electrons transferred per oxygen and HO2- yield of materials synthesized at different temperatures, and chronoamperometry of PFU-800 and Pt-C-10%.
