In this study, two carbazole-triazine derivatives with cyanuric acid and melamine cores, namely 2,4,6-tris(4-(9H-carbazole-9-yl)butoxy)-1,3,5-triazine (CB) and N2,N4,N-6-tris(4-(9H-carbazole-9-yl)butyl)-1,3,5-triazine-2,4,6-triamine (MB), were synthesized and investigated as electrocatalysts for the electrooxidation of hydrazine, an environmentally benign fuel with high energy density. These organic electrocatalysts were prepared through nucleophilic substitution reactions and structurally characterized by FT-IR, NMR, XRD, SEM, and TEM analyses. Their electrochemical performance was evaluated by cyclic voltammetry (CV), chronoamperometry (CA), and electrochemical impedance spectroscopy (EIS). The MB compound exhibited a current density of 16.97 mA/cm2, which is 7.68 mA/cm2 higher than that of CB. CA and EIS analyses further revealed that MB possesses higher stability and lower charge-transfer resistance than CB. These findings demonstrate that nitrogen-rich carbazole-triazine derivatives are promising metal-free anode electrocatalysts for efficient hydrazine oxidation.
