Heterostructure of Fe2O3 doped Alstonia Scholaris wood waste derived activated carbon based electrode for supercapacitor applications

Abstract

The production of environmentally friendly and long-lasting supercapacitor electrodes employing activated carbons obtained from industrial wood waste from Alstonia Scholaris by traditional chemical activation using H2SO4 at High temperature activation is shown in this paper. The new traits of metal oxide (Fe2O3) doped Alstonia Scholaris wood derived activated carbon employing a slow precipitation technique. The produced activated carbon and the Fe2O3 doped activated carbon samples were examined using a variety of analytical methods, including XRD, FESEM, TEM-HRTEM, elemental mapping, N2 adsorption-desorption, Raman, XPS, and VSM. The BET result of prepared Fe2O3 doped activated carbon exhibits high surface area of 443 m2g−1. However, the assembled ASC cell exhibits high energy density of 38 Wh/kg and power density of 3181 W/kg. This work focuses on an innovative, straightforward process for producing low cost activated carbon from waste wood sources, which might have useful applications in the energy storage system.
