In this research work, pure magnetite Fe3O4 (F), bismuth doped (FB), reduced graphene oxide (FR) and bismuth-rGO co (FBR) were prepared successfully by facile co-precipitation technique. The structural, optical, FTIR morphological analysis of the samples carried out. XPS- Photo electron spectroscopy indicates presence relevant elements oxidation states. BET surface shows enhanced area in co-doped due to addition rGO. photocatalytic activity materials (F, FB, FR, FBR) against several organic dyes [MB, Rho-b, Congo red (CR)] was investigated. antibacterial studied using disc diffusion method various gram positive negative bacterium, result reveals that nano composite high antimicrobial activity. synthesised also used as electrode for supercapacitors. electrochemical performance FBR-based supercapacitor device good, it exhibited a specific capacitance 888 Fg-1 at current density 1 Ag-1. From CV analysis, measured 315 three-electrode configuration. symmetric has been constructed rGO 312 Fg-1, energy 62.30 W h Kg-1, power 719.79 Kg-1 0.3 Ag-1 with notable cyclic stability about 89% had average capacity retention excellent coulombic efficiency which is 95% up 8000 cycles retained even after 18,000 cycles.
