Synthesis of self-assembled mesoporous 3D In₂O₃ hierarchical micro flowers composed of nanosheets and their electrochemical properties

Abstract

This report describes the methodology for the fabrication of mesoporous In2O3 microflowers by hydrothermal and calcination procedures in which In(OH)3/In2S3 acts as an intermediate.

One-Pot Synthesis of rGO@Cu2V2O7 Nanocomposite as High Stabled Electrode for Symmetric Electrochemical Capacitors

“…The following factors can be used to describe how specific capacitance varies with the scan rate [i] at high scan rates ion from the electrolyte have less time to penetrate into the electrode material it denotes that sufficient amount of charge stored on the surface which results in decrease of specific capacitance [ii] at low sweep rate K + ion have the ability to move to and fro towards surface of the electrode [iii] the incorporation of rGO in the Cu 2 V 2 O 7 composite increases the effective specific surface area and reduces the diffusion and mobility routes for electrolyte ions and [iv] the frequent relations between rGO and Cu 2 V 2 O 7 enhances electrical conductivity. 47 Henceforth, Cu 2 V 2 O 7 and rGO@Cu 2 V 2 O 7 electrodes were investigated by GCD analysis shows in Figs. 5c to 5d.…”
