Synthesis of CoMoO۴@RGO/PPY as high performance supercapacitor electrode

In this study, Nanoparticles of cobalt molybdate (CoMoO۴) binary metal oxide and its composite with reduced graphene oxide and Poly pyrrole was synthesised by electrochemical deposition method on stainless steel and used as a supercapacitor electrode to achieve proper electrochemical properties and high stability. X-ray diffraction spetroscopy (XRD), field emission-scanning electron microscopy (FESEM) and energy dispersive X-ray (EDX) analysis confirmed the presence of RGO, Polypyrrole and CoMoO۴ in our synthesized nano composite. The synthesized nano coposite was able to show its optimized electrochemical properties such that, specific capacitance at current density of ۳ A/g and in asolution of potassium hydrate (KOH) ۳ molar as an electrolyte was measured ۳۵۲٫۵ F/g. Also cyclic lifestability after ۱۰۰۰ cycles was measured ۸۶% .
