Development and analysis of zeolite-based electrodes drived from fly ash for supercapacitor application

DEVLOPMENT AND ANALYSIS OF ZEOLITE-BASED ELECTRODES DERIVED FROM FLY ASH FOR SUPERCAPACITOR APPLICATION

Abstract

In the current global scenario, the pressing challenges of energy scarcity and environmental degradation profoundly impact the pursuit of sustainable development. The present study involved the preparation of zeolite by utilizing waste material (fly ash) obtained from a thermal power plant. An easy and cost-effective method for utilizing waste to generate useful material is provided by hydrothermal crystallization for the preparation of zeolite. To analyze the as-synthesized material, X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, Field emission scanning electron microscopy (FE-SEM), and Brunauer-Emmett-Teller (BET) analysis were used. The electrochemical investigation of as prepared material illustrates excellent capacitive behavior and shows a specific capacitance of 25 Fg^-1 at 0.5 Ag^-1 with an unprecedented specific surface area of 118.812 m²g⁻¹. This study reveals the pathway of waste management in the direction of developing energy harvesting material.
