에너지 저장 장치 활용을 위한 간단한 폐지 탄화 방법 개발

초록

The continuous growth of global population has led to a substantial increase in the demand for and production of various types of papers, which in turn, exacerbated the urgent need for waste management techniques to mitigate the environmental impact of these materials. Herein, we have developed a simple and rapid carbonization method for synthesizing valuable carbon materials from waste papers. Physical and chemical characteristics of the prepared waste paper derived carbons (WPDCs) were investigated. Next, the carbons were utilized in the fabrication of supercapacitor electrodes. Electrochemical performance of the WPDCs was systematically analyzed, and their feasibility for energy storage application was evaluated. Among the fabricated WPDCs, microwave-assisted waste paper carbon (MWC) exhibited electrical double layer capacitance and a maximum specific capacitance of 119 F/g at a scan rate of 5 mV/s. These findings provide a solution to the waste management problem by presenting an alternative way to reuse waste papers via the production of carbon materials.
