Synthesis, Characterization and Electrochemical Study of Graphene Oxide-Multi Walled Carbon Nanotube-Manganese Oxide-Polyaniline Electrode as Supercapacitor

• MWCNT has improved the electrochemical behavior of GO.
• GO-MWCNT-MnO2-PANI (GMMP) revealed the best supercapacitive behavior.
• The specific capacitance of GMP, GMM and GMMP was calculated to be 127.85, 87.56 and 173.00 (mF. cm−2), respectively.
• The specific capacitance of GMMP was nearly 14.5 times greater than G.
• The improved electrochemical properties in G
