Abstract

The stability of pyrolyzedMn–Co/polypyrrole (PPy) nanocomposites towards theOxygen Reduction Reaction (ORR) in alkaline solution,was studiedwith a close-knit group of complementarymicroscopic and space-resolved spectroscopic approaches: Atomic Force Microscopy (AFM), Scanning and High-Resolution Transmission Electron Microscopy (SEM, HRTEM) and identical-location Scanning PhotoElectron Microscopy (SPEM). Tracking quasi-in situ the morphochemical evolution of the Mn–Co/PPy catalyst upon electrochemical aging under ORR conditions by this multi-technique approach, has allowed to clarify the key physico-chemical processes underlying the dramatic impact of Co additions to stability improvement.
