CO2 Activation of Bamboo Residue after Hydrothermal Treatment and Performance As an EDLC Electrode.
RSC advances(2021)
摘要
CO2 activation of the solid residue of bamboo after hydrothermal treatment, which is used for the production of xylo-oligosaccharide, was investigated in detail. The reference temperature for carbonization and CO2 activation was 800 °C. The activated carbon from a solid residue was demonstrated to have a higher potential for making EDLC electrodes than bamboo activated carbon thanks to its very low ash content (almost 0) and high porosity structure with a BET surface area up to ca. 2150 m2 g-1. The electrochemical performance of ELDC electrodes prepared from solid residue-derived activated carbon in 1 M H2SO4 aqueous solution was measured and well compared with carbon from bamboo. Through investigation, it is clear that the capacitance of the electrode made from the solid residue has a better capacity than that of raw bamboo.
