本研究采用盐酸洗涤法对天然芦荟进行了纯化。以乳糖为碳源，纯柠檬酸为硬模板剂，室温常压浸渍法制备了介孔碳材料。通过相关测试确定了介孔碳材料的形貌和结构。进行电化学测试以评估材料的电化学性能。结果表明，AT-5 M纯化炭具有最大的比表面积，所制备的炭材料呈现部分束状结构，比表面积和总孔容分别为593 m2 g − 1和1.021 cm 3 g −1。恒电流充放电测试表明，所制备的碳材料具有良好的储能性能。当电流密度为625 mA g-1时，比电容达到180 F g-1。该材料即使在高扫描速率（200 mV s-1）下也显示出典型循环伏安曲线的准矩形特征，表明它们具有优异的倍率容量。交流阻抗测试结果表明，该材料为典型的多孔电极材料，其结合电阻为0.525 Ω。1000次恒流充放电循环后，比电容留存率达到95. 32%，表明材料具有上级的循环稳定性。
In this study, natural attapulgite was purified by hydrochloric acid washing. Mesoporous carbon materials were prepared by atmospheric pressure impregnation at room temperature using pure attapulgite as a hard template and lactose as a carbon source. Relevant tests were used to determine the morphology and structure of the mesoporous carbon materials. Electrochemical tests were performed to evaluate the electrochemical performance of the materials. Results show that the AT-5M purified attapulgite possessed maximum specific surface area, and the as-prepared carbon materials exhibited partial fasciculus with specific surface area and total pore volume of 593 m2g−1and 1.021 cm3g−1, respectively. The constant current charge/discharge tests showed that the as-prepared carbon materials demonstrated excellent energy storage capacity. When the current density was 625 mA g−1, the specific capacitance reached 180 F g−1. The materials showed quasi-rectangular features of typical cyclic voltammetry curves even at a high scan rate (200 mV s−1), indicating that they possessed excellent rate capacity. AC impedance tests showed that the materials were typical porous electrode materials with combination resistance of 0.525 Ω. The specific capacitance retention rate reached 95.32 % after 1000 constant current charge/discharge cycles, indicating that the materials had superior cyclic stability.
