Abstract In this work, a facile method to prepare commercial nano-Bi2O3/carbon composites with high pseudocapacitive properties was presented. The inorganic-organic composites synthesized by using commercial bismuth oxide and active carbon with different weight ratio. The composites were characterized using microscopic, spectroscopic, and diffractive methods. Our assessments confirmed that active carbons were successfully doped with commercial Bi2O3 nanoparticles with different dopant rates. The composites exhibited a maximum specific capacitance of 517 F/g at a current density of 1 A/g for 20% Bi2O3 nanoparticle doped activated carbon samples. Augmented discharging time was also achieved for increased Bi2O3 nanoparticle doping rate. Increased Bi2O3 dopant rate also increased the calculated specific capacitance.
