Abstract:
In the recent years, the nitrogen-containing carbon nanostructures (NCNS) have received increasing attention especially because of their applicability in the fabrication of new catalysts, electrocatalysts, and electrode material for supercapacitors. The aim of this study is the investigation of electrocatalytic activity toward oxygen reduction reaction of NCNS. The carbonization of polyaniline nanostructures as nitrogen containing precursors was used for the preparation of NCNS. Polyaniline nanostructures were synthesized using three different template free polymerization methods. In the present work we compared the efficiency of these materials for oxygen reduction reaction (ORR) in alkaline media. The electrochemical behavior was correlated with data obtained from X-ray Photoelectron Spectroscopy, Scanning Electron Microscopy and Raman Spectroscopy.
