Abstract

A lignocellulosic biomass, durian shell, modified by radiolytic oxidizing species from gamma and electron beam irradiations, has been used as a starting material for activated carbon (AC) production. Facile hydrothermal carbonization with ZnCl₂/FeCl₃ and physical activation were employed in addition. The physicochemical and energy storage properties of the graphitic carbons were investigated using Field Emission Scanning Electron Microscope (FESEM), N₂ adsorption-desorption, Brunauer-Emmett-Teller (BET), Fourier Transform Infrared Spectroscopy (FTIR), X-ray Diffraction (XRD), Raman spectroscopy, Cyclic Voltammetry (CV), Galvanostatic Charge-Discharge (GCD) and Electrochemical Impedance Spectroscopy (EIS). Biomass modification by radiolytic oxidizing species aided in improving the energy storage properties of the resultant ACs without significantly changing the textural qualities. The radiation type played an important role on the surface functional groups, basal plane, and pore structures of the graphitic materials. The energy storage mechanism was based on a combination of EDLC and pseudo capacitances with high Coulombic efficiency. The highest specific capacitance obtained was 325.20 F/g providing capacity retention of 94.79 % after 10,000 cycles. A promising method of AC production for energy storage application has therefore been successfully demonstrated.

辐射加工榴莲壳制备的活性炭储能应用

榴莲壳是一种木质纤维素生物质，经伽马射线和电子束辐照的放射性氧化物改性后，被用作生产活性炭（AC）的起始材料。此外，还采用了 ZnCl2/FeCl3 水热碳化法和物理活化法。使用场发射扫描电子显微镜（FESEM）、N2 吸附-解吸、Brunauer-Emmett-Teller（BET）、傅立叶变换红外光谱（FTIR）、X 射线衍射（XRD）、拉曼光谱、循环伏安法（CV）、Galvanostatic Charge-Discharge （GCD）和电化学阻抗谱（EIS）对石墨碳的物理化学和储能特性进行了研究。用放射性氧化物对生物质进行改性有助于提高所制交流电的储能特性，而不会明显改变其质地。辐射类型对石墨材料的表面官能团、基底面和孔隙结构起着重要作用。储能机制基于具有高库仑效率的 EDLC 和伪电容的组合。获得的最高比电容为 325.20 F/g，经过 10,000 次循环后，电容保持率为 94.79%。因此，一种用于储能应用的交流电生产方法已得到成功验证。

期刊介绍： Carbon Resources Conversion (CRC) publishes fundamental studies and industrial developments regarding relevant technologies aiming for the clean, efficient, value-added, and low-carbon utilization of carbon-containing resources as fuel for energy and as feedstock for materials or chemicals from, for example, fossil fuels, biomass, syngas, CO2, hydrocarbons, and organic wastes via physical, thermal, chemical, biological, and other technical methods. CRC also publishes scientific and engineering studies on resource characterization and pretreatment, carbon material innovation and production, clean technologies related to carbon resource conversion and utilization, and various process-supporting technologies, including on-line or off-line measurement and monitoring, modeling, simulations focused on safe and efficient process operation and control, and process and equipment optimization.
