Understanding the impact of nitrogen doping and/or amine functionalization of reduced graphene oxide via hydrothermal routes for supercapacitor applications

Nitrogen doping and amine-functionalization have previously been used to improve the capacitance of graphene-based materials, however there is a lack of understanding on the mechanisms by which these modifications impact the electrochemical behavior and electrochemical supercapacitor performance, or if these approaches can be combined to achieve synergistic benefits. Herein, we investigate this by synthesizing reduced graphene oxide (HtrGO) …
