제목 Preparation of Resin-based Activated Carbons and Their Capacitance for Supercapacitor Materials
초록 In this work, activated carbons (ACs) with high porosity are synthesized from polystyrene-based ion exchange resin (PIR) by potassium carbonate (K2CO3) chemical activation, and the influence of the K2CO3-to-PIR ratio on the porosity of the ACs and electrochemical characteristics are investigated. The textural properties of the ACs were investigated by N2/77 K adsorption isotherms via Brunauer-Emmett-Teller (BET) equation. The electrochemical performance of ACs was determined by cyclic voltammetry (CV) and galvanostatic charge/discharge characteristics in 6 M KOH electrolyte. As a result, PIR is successfully converted into ACs with well-developed micro and mesopores. The specific surface areas and pore volumes are increased with an increase in the K2CO3-to-PIR ratio. The electrochemical performance of the PIR-based ACs is enhanced by high specific surface area and oxygen functional groups.
