Abstract Manganese dioxide (MnO 2 ) nanoparticles were modified by graphitic carbon nitride (GCN) and polylpyrrole (Ppy) to enhance their electrochemical performance. The surface influence, crystalline structure, performance of the Ppy/GCN/MnO material characterized compared with those pristine MnO . It is found that modification can improve structural stability without decreasing its available specific capacitance. properties synthesized electrode evaluated using cyclic voltammetry (CV) AC impedance techniques in 5 M KOH electrolyte. Specific capacitances 486, 815, 921, 1377 F/g obtained for , Ppy/MnO GCN/MnO respectively, at A/g. This improvement attributed synergistic effect GCN Ppy material. has average energy power densities 172 Wh kg −1 2065 W respectively. Only % capacitance’s initial value lost after 10,000 cycles. resulting nanocomposite had very stable porous layered structures. work demonstrates nanomaterials exhibit good are materials supercapacitor applications.

Benzene 1,3,5-tricarboxylic acid Metal organic frameworks (BTC MOFs), a class of exceptional porous materials with multifunctional capabilities and capable nanogeometries, have drawn lot attention lately from researchers as potential for supercapacitor electrodes. This study introduces novel Ni-MOF/PANI/GO ternary nanocomposite synthesized through cost-effective chemical oxidative polymerization method. Graphene oxide (GO) was by modified Hummers’ framework (MOF) Hydrothermal Method Polyaniline (PANI) method to the effect GO PANI electrochemical properties Ni-MOF. Structural characterization morphology developed carried out powder X-ray diffraction (XRD), FTIR spectroscopy, UV-Vis PL spectroscopy. As result, grown structure having an average crystalline size 13.767 nm successfully confirmed XRD analysis. Different bonds & transmittance peaks are analyzed FTIR. Also D G bands also explained during Raman Analysis. The optical band gap (E_g) approximately ~ 4.02 eV spectra. Electrochemical performed using CV, GCD EIS analysis in 3 M KOH solution. CV revealed that composite showed maximum specific capacitance 206 Fg^{− 1} at 1 mVs^{− charge retention ca. 81.5% after 5000 charge-discharge cycles. aim this is synthesize evaluate its applications.}
