Herein, PANI has been prepared via in situ facile and low‐cost electro‐polymerization method. At a current density of 0.2 A g −1 , the supercapacitor using PANI electrode shows the specific capacitances of 203.0 F g −1 in 1 M H 2 SO 4 electrolyte. To further improve the electrochemical activity of PANI electrode, the transition metal ions M 2+ (M 2+ = Ni 2+ , Co 2+ , Mn 2+ , and Cu 2+ ) have been doped into PANI electrode via the same electro‐polymerization method. And the supercapacitor with the different doped‐PANI electrode generates the specific capacitances of 364.3, 326.1, 258.5, and 250.6 F g −1 respectively from PANI‐Ni 2+ , PANI‐Co 2+ , PANI‐Mn 2+ , and PANI‐Cu 2+ , which were superior to 79.5%, 60.6%,27.3%, and 23.4% of the pristine PANI based counterpart under the same test conditions and method. The favorable performances make the different doped‐PANI act as a new resource of the high performance electrode materials of supercapacitor.23:T46d,To replace precious Pt-based counter electrodes (CEs) with a low-cost Pt-free catalyst of CEs is still a motivating hotspot to decrease the fabrication cost of dye-sensitized solar cells (DSSCs). Herein, four different V₂O₃@C composite catalysts were synthesized by pyrolysis of a precursor under N₂ flow at 1100 °C and further served as catalytic materials of CEs for the encapsulation of DSSCs. The precursors of V₂O₃@C composites have been prepared via a sol-gel method using different proportions of V₂O₅ with soluble starch in a H₂O₂ solution. Power conversion efficiencies (PCEs) of 3.59, 4.79, 5.15, and 5.06% were obtained from different V₂O₃@C composites, with soluble starch-to-V₂O₅ mass ratios (S/V) of 1:2, 1:1, 2:1, and 4:1, respectively, as CEs to reduce iodide/triiodide in DSSCs. The improvement of electrode performance is due to the combined effects on the increased specific surface area and the enhanced conductivity of V₂O₃@C composite catalysts.
