摘要
在本研究中，开发了一种通过生产活性炭来管理海洋塑料废物的方法。测定了在选定温度和活化剂重量比下制备的海洋塑料基活性炭的比表面积、微孔体积和介孔体积，并对其比电容和超级电容器电极性能进行了评价。在活化温度为800℃，原料与8 M KOH的质量比为1:7的条件下，获得了201F/g的比电容和2389 m2/g的高比表面积。因此，海洋塑料垃圾活性炭可以作为超级电容器的电极材料。
Recycling marine plastic waste to energy storage devices
In this study, a method was developed for the management of marine plastic waste via the production of activated carbon. The specific surface area, micropore volume, and mesopore volume of marine-plastic-based activated carbon prepared at selected temperatures and using selected activator weight ratios were measured, and the specific capacitance and supercapacitor electrode performance were evaluated. At an activation temperature of 800 °C and a raw material to 8 M KOH weight ratio of 1:7, a specific capacitance of 201F/g and a high surface area of 2389 m2/g were obtained. Therefore, marine plastic waste-based activated carbon can be used as the electrode material in supercapacitors.
