Enhancement of quaternary nitrogen doping of graphene oxide via chemical reduction prior to thermal annealing and an investigation of its electrochemical properties†
Abstract
A simple and efficient method to enhance the quaternary C bonds and simultaneously decrease the atomic oxygen concentration. The reduced graphene oxide (RGO) was then annealed in the presence of
C when compared to the atomic oxygen concentration. In addition, due to the decreased atomic oxygen concentration, the electro-conductivity was enhanced. Cyclic voltammograms (CVs) of 5 mM K3Fe(CN)6 and 2 mM H2O2 were used to examine the electrochemical response of the quaternary N-maximized RGO. An improvement in electrocatalytic
