Mixed manganese oxidesPolypyrroleOxygen reductionElectrocatalysisNanocompositesX-ray photoelectron microspectroscopyThe stability of pyrolyzed Mn–Co/polypyrrole (PPy) nanocomposites towards the Oxygen Reduction Reaction (ORR)
in alkaline solution, was studied with a close-knit group of complementary microscopic 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.20162016-07-22 12:08:27Delo ni kategorizirano2526COBISS_ID: 4446459NUK URN: URN:SI:UNG:REP:YVQ5B4Z5sl
