Through a simple method bismuth sulfide nanosheets were synthesized and located cobal oxide nanostructures on bismuth sulfide substrate. With different analysis methods such as Energy-dispersive X-ray (EDX),scanning electron microscopy(SEM) and cyclic voltammetry (CV) techiques were confirmed immobilization of cobalt oxide componds on to bismuth sulfide nanosheets. High repeatability of electrochemical behavior confirmed will strong bonding and stability of the immobilized componds on to bismuth sulfide surface. The results revealed that composite containing show suitable electrochemical and capacity for using in design of supercapacitor. The use of the composites as a supercapacitor for compond on bismuth sulfide exhibit capacitance 1400 F/gr.
