Modern energy and ecological sustainability can be accomplished in part, by using activated bio char-based electrodes made from biomass waste in energy-producing devices like metal-air batteries and fuel cells. Herein, a simple method of combining Pyrolysis graphitization with DC glow discharge plasma is used to create highly disorder carbonaceous materials incorporating surface functional groups from a readily available and inexpensive bio waste of peanut shells. The synthesized activated Peanut shell carbon material displays remarkable supercapacitance performance in 2 M KOH at elevated specific capacitances (537 Fg⁻¹ at 10 mVs⁻¹) and catalytic ability for the oxygen reduction response at a half-wave peak of 0.19 V. Water contact angle and dispersion studies showed a considerable improvement in the surface’s hydrophilic following plasma treatment, and FTIR and Raman spectroscopy were also used to evaluate the surface’s functional group and micro structure. In this study, a simple, affordable, and environmentally friendly method for making activated dis ordered carbon is revealed. It is then investigated as a potential electrode for supercapacitor, metal air battery, fuel cell applications.

冷等离子体暴露的活化花生壳碳作为铝空气电池电极的优异扩散性能

现代能源和生态可持续性可以通过在金属空气电池和燃料电池等能源生产设备中使用由生物质废物制成的活性生物炭电极来部分实现。在此，使用一种将热解石墨化与直流辉光放电等离子体相结合的简单方法，从容易获得且廉价的花生壳生物废物中产生结合表面官能团的高度无序碳质材料。合成的活化花生壳碳材料在 2 M KOH 中以较高的比电容（10 mVs ^{-1时为 537 Fg -1}）表现出卓越的超级电容性能，并在 0.19 V 的半波峰处表现出氧还原响应的催化能力。 水接触角度和色散研究表明，等离子处理后表面的亲水性有了相当大的改善，并且还使用FTIR和拉曼光谱来评估表面的官能团和微观结构。在这项研究中，揭示了一种简单、经济且环保的制造活性无序碳的方法。然后将其作为超级电容器、金属空气电池、燃料电池应用的潜在电极进行研究。
