- Description
- The rise in energy needs in our society has enhanced the requirement for energy production and storage studies. The electrocatalytic hydrogen evolution reaction and supercapattery studies pave the way for producing and storing energy effectively. There is a lot of ongoing work on synthesizing efficient electrocatalysts for such energy related applications. In this study, polypyrrole/V2O5/MnO2 electrocatalyst is synthesized, and various characterization techniques have been utilized for analyzing the formation of the composite. The N2 adsorption-desorption analysis demonstrates the average surface area of the polymer composite as 136.3 m2/g. The high average surface area value suggests the availability of surface active sites on the synthesized polymer composite for energy production and storage. The polypyrrole/V2O5/MnO2 electrocatalyst shows an overpotential of 192 mV and a specific capacity of 1736.1C/g. The synthesized catalyst is used for fabricating an asymmetric supercapacitor, which demonstrates an energy density of 46.8 Wh/kg and a power density of 714.2 W/kg. Polypyrrole/V2O5/MnO2 electrocatalyst is proven to be a competent material for supplementing the energy requirements of our society. 2025 Hydrogen Energy Publications LLC
