Details
This study presents the development of carbon-based multiphase metal oxide nanocomposites (CNF@MOx) as electrode materials for supercapacitors, fabricated via electrospinning and annealing in an argon atmosphere.
This study presents the development of carbon-based multiphase metal oxide nanocomposites (CNF@MOx; M = Ag, Mn, Bi, Fe) incorporating silver, manganese, bismuth, and iron nanoparticles within polyacrylonitrile (PAN)-derived carbon nanofibers.
- Fabrication: Produced via the electrospinning technique followed by annealing in an argon atmosphere.
- Structural Properties: The nanofibers exhibit a uniform structure with diameters ranging from 559 to 830 nm and embedded nanoparticles of 9-21 nm.
- Electrochemical Performance: CNF@Ag/Mn/Bi/Fe-20 achieved a maximum specific capacitance of 156 F g⁻¹ at a scan rate of 2 mV s⁻¹.
- Stability: Retains over 96% of its capacitance after 1400 charge-discharge cycles.
- Mechanism: The synergistic combination of electric double-layer capacitance and redox-based charge storage enhances performance.
Objective
The project aims to synthesize and develop metal oxide-doped carbon nanofibers, analyze their physical and electrochemical properties, and evaluate their performance as supercapacitor electrodes.
- Synthesize and develop multiphase metal oxide-doped carbon nanofibers (CNF@MOx; M = Ag, Mn, Bi, Fe) using electrospinning and calcination in an argon atmosphere.
- Analyze the structure and physical properties of the synthesized materials, including particle size, porosity, and metal oxide oxidation states.
- Investigate the electrochemical properties of the synthesized materials to evaluate their supercapacitor charge storage capacity.
- Compare the performance of the synthesized electrode materials with existing materials, considering specific capacitance, charge-discharge cycle stability, and energy storage mechanisms.
