Energy-controlled supercapacitors based on polybenzidine-oxidant-GO hybrid electrodes with vanadate and dichromate redox chemistry (opens in new tab)

In this study, polybenzidine (PB) was successfully synthesized in situ on anodized graphite substrates (AGS) using dichromate (PB-C/AGS) and vanadate (PB-V/AGS) oxidants, and their electrochemical performance was systematically evaluated for supercapacitor applications. Structural analyses by ATR-IR, Raman, FE-SEM, EDX, and XRD confirmed the successful polymerization and incorporation of metal oxide species. By employing two oxidants with distinct redox potentials, the polymerization pathway,...
