采用来自中国新疆地区的生物质———恰玛古为碳前驱体, 充分利用其体内固有的孔道结构, 并在此基础上进行预碳化和活化, 设计制备了多孔生物质衍生炭材料 (BDPC) 。利用扫描电子显微镜、X射线衍射、Raman光谱、X射线光电子能谱和氮气吸/脱附测试对材料进行结构与物相分析；通过循环伏安法、恒流充放电、循环、倍率和电化学阻抗测试表征了该材料应用于储钠阳极的电化学性能。结果表明, BDPC-600因含有氮、氧杂原子 (含量分别为3. 36at. %和7. 61at. %) , 故具有良好的储钠性能：当电流密度为0. 1A/g时, 经过100次循环充放电过程后, 可逆容量为187. 7mAh/g, 容量保持率为88. 7%。此外, BDPC-900由于具有较大的比表面积 (2396. 60m2/g) 和孔容 (1. 70cm3/g) , 故具有优异的倍率性能。

Biomass-derived porous carbon (BDPC) was designed and prepared from Qamgur, a biomass from Xinjiang, China, as the carbon precursor, by pre-carbonization and activation, while retaining Qamgur’s inherent pore structure. The microstructure, phase composition and pore structure of the material were analyzed by scanning electron microscope (SEM) , X-ray diffraction (XRD) , Raman spectroscopy, X-ray photoelectron spectroscopy (XPS) and nitrogen adsorption desorption test; The electrochemical properties of the material as a sodium storage anode were characterized by cyclic voltammetry, constant current charge-discharge, cycling, magnification and electrochemical impedance measurements. The results show that BDPC- 600 has good sodium storage performance because it contains nitrogen and oxygen heteroatoms (the contents are 3. 36 at. % and 7. 61 at. %, respectively) . At 0. 1A/g current density, after 100 cycles of charge and discharge, the reversible capacity is 187. 7mAh/g, and the capacity retention rate is 88. 7%. In addition, BDPC-900 has excellent magnification performance due to its large specific surface area (2396. 60 m2/g) and pore volume (1. 70cm3/g) .
