In the production of activated carbons (ACs), glucose as a precursor is prone to producing the graphitic char intermediates after carbonization, which are difficult to be activated in the subsequent activation. In order to obtain a desirable specific surface area, either twice activation after carbonization or hydrothermal treatments of glucose before activation is applied. In this research, the direct activation of glucose has been executed to produce honeycombed ACs via deoxygenation of the glucose precursor in the KOH aqueous solution for appropriate time at room temperature. It is found that when glucose is subjected to the alkaline circumstance, dehydration and polymerization reactions increase the C/O ratio while the degradation and oxidation decrease the C/O ratio. The AC from the deoxygenated product with the highest C/O ratio has a superior specific surface area of 1912 m² g⁻¹ which is much higher than 130 m² g⁻¹ for the AC by the conventional two-step method. The Honeycombed morphology and the specific surface increased by one order of magnitude lead to good performance of 268 F g⁻¹ in the KOH and 24.5 Wh kg⁻¹ in the KBr electrolyte.

在活性炭（ACs）的生产中，葡萄糖作为前驱体，碳化后容易产生石墨炭中间体，难以在后续活化中活化。为了获得理想的比表面积，在碳化后进行两次活化或在活化前对葡萄糖进行水热处理。在这项研究中，通过直接激活葡萄糖来生产蜂窝状活性炭。在室温下使葡萄糖前体在 KOH 水溶液中脱氧适当时间。发现葡萄糖在碱性环境下，脱水和聚合反应使C/O比升高，而降解和氧化使C/O比降低。来自具有最高 C/O 比的脱氧产物的活性炭具有 1912 m ² g ^-1的优异比表面积，远高于传统两步法^活性炭的130 m ² g ^-1。蜂窝状形态和比表面积增加一个数量级，导致KOH中 268 F g ^-1和KBr 电解质中24.5 Wh kg ^{-1 的}良好性能。
