In the present paper, the electrochemical behavior and the properties of two modified glassy carbon (GC) electrodes used for quantification of gallic acid in sweet wines were compared. A comparative study was conducted between titanium nitride- or wolfram carbide-doped reduced graphene oxide, labeled as TNrGO and WCrGO, respectively, modified GC electrodes, which are promising composite nanomaterials for electroanalytical applications. For the first time, WCrGO was synthesized and its electroanalytical properties compared with those of TNrGO. Results showed that the proposed materials exhibited enhanced characteristics, e.g., low limits of detection (1.1 mu M and 3.1 mu M for TNrGO and WCrGO, respectively), wide linear ranges (for TNrGO 4.5-76 mu M and for WCrGO 10-100 mu M), low adsorption, and low background current, which make them promising candidates for electrochemical sensing applications.
