Synthesis of Polybenzidine-Heptamolybdate Nanoneedles onto anodizedgraphite sheet as a new supercapacitor electrode

Today, researchers are focusing on the development of various new nanomaterials for use in thesupercapacitor industry. This study introduces a new material, polybenzidine-heptamolybdatenanoneedles (PB-Mo۷O۴۲ Nns), which has been grown for the first time on an anodic exfoliatedgraphene oxide sheet (GOS) substrate. The PB-Mo۷O۴۲ Nns/GOS electrode was easily fabricatedthrough the anodization of a graphite sheet electrode followed by the polymerization of benzidine inthe presence of ammonium heptamolybdate. The results of the FE-SEM showed that PB-Mo۷O۴۲grows on the GOS electrode in a special form with nanoneedle morphology. The electrochemicalstudy demonstrated that the fabricated electrode has an excellent capacitance of ۱.۱۱۰۱ mF cm-۴ at ۱۰۱mA cm-۴ in ۱ M H۴SO۲.
