Soot is used as an electrode material for possible supercapacitance applications. The carbonaceous product is collected from a domestic heating system and possesses a naturally developed high surface area, which is one of the key requirements for such applications. The low-molecular-weight compounds in the soot are evaporated and carbonized by heat treatment of the samples in the range 400–800 °C. The heating at different temperatures causes different degrees of carbonization, functional groups removal, and samples’ stabilization. The capacitance is compared of prototypes with electrodes made from materials treated at different temperatures. The prototype samples are investigated by Fourier transform infrared spectroscopy and transmission electron microscopy, revealing sequentially removed functional groups and a variety of carbon structures, such as graphene sheets, monocrystalline carbon particles, and onion-like structures.

用于超级电容器的热稳定烟尘

烟灰被用作可能的超级电容应用的电极材料。碳质产品是从家庭加热系统中收集的，具有自然形成的高表面积，这是此类应用的关键要求之一。通过在 400-800 °C 范围内对样品进行热处理，烟灰中的低分子量化合物被蒸发和碳化。在不同温度下加热会导致不同程度的碳化、官能团去除和样品的稳定。电容与由在不同温度处理的材料制成的电极的原型进行比较。通过傅里叶变换红外光谱和透射电子显微镜研究原型样品，揭示了顺序去除的官能团和各种碳结构，
