Heteroatom-doped porous carbons have attracted great concern owing to their enhanced physicochemical property. In this study, a hierarchically porous sulfur- and oxygen-co-doped carbon (PSOC) is obtained through direct carbon dioxide activation of poly(3,4-ethylenedioxythiophene) with abundant sulfur and oxygen atoms in the polymer backbone. Both sulfur and oxygen heteroatoms are introduced into carbon matrix through a rational preparation approach. The morphology, microstructure, and chemical property of the as-prepared PSOC have been analyzed by using various characterization methods, including scanning/transmission electron microscopy, nitrogen sorption test, Raman spectroscopy, and X-ray photoelectron spectroscopy. PSOC displays a high specific surface area (1160 m² g⁻¹) and hierarchically porous structure (micropores, mesopores, and macropores). Owing to its excellent surface property and porosity parameters, PSOC exhibits a good gas adsorption capacity (carbon dioxide: 16.6 wt %; methane: 2.7 wt %) at 273 K under 1.0 bar when used as a gas sorbent. In addition, PSOC as an anode material shows a high reversible capacity of 931 mA h g⁻¹ at 100 mA g⁻¹ and excellent cycling performance (504 mA h g⁻¹ at 200 mA g⁻¹ after 200 cycles). As a result, the as-prepared PSOC demonstrates a promising potential in the fields of gas adsorption and energy storage.

杂原子掺杂的多孔碳由于其增强的理化性质而引起了极大的关注。在这项研究中，通过在聚合物主链中具有大量硫和氧原子的聚（3,4-乙撑二氧噻吩）进行直接二氧化碳活化，获得了分层多孔的硫和氧共掺杂碳（PSOC）。硫和氧杂原子都通过合理的制备方法引入碳基质中。通过使用各种表征方法，包括扫描/透射电子显微镜，氮吸附测试，拉曼光谱和X射线光电子能谱，分析了所制备PSOC的形态，微观结构和化学性质。PSOC显示高比表面积（1160 m ²  g ^-1）和分层多孔结构（微孔，中孔和大孔）。由于其优异的表面性能和孔隙率参数，当用作气体吸附剂时，PSOC在273 K，1.0 bar下表现出良好的气体吸附能力（二氧化碳：16.6 wt％；甲烷：2.7 wt％）。此外，作为负极材料的PSOC在100 mA g ^-1时显示出931 mA hg ^-1的高可逆容量，并具有出色的循环性能（200个循环后在200 mA g ^-1时显示504 mA hg ^-1）。结果，所制备的PSOC显示出在气体吸附和能量存储领域中的有希望的潜力。
