Abstract

In the current work, we explored the direct synthesis of S-doped porous carbons employing cesium methanesulfonate as a novel bifunctional chemical activator. The obtained carbons showed high surface area (654–2264 m²/g) and high S content (6.56–15.13 wt%). Effects of activation temperature and cesium methanesulfonate amount on the carbons’ properties were also studied. The obtained carbons showed CO₂ uptake of 3.58–4.76 mmol/g at 0 °C and 1 bar. Effects of textural properties and S-doping on CO₂ adsorption performances were discussed.

制备用于二氧化碳吸附的掺 S 多孔碳的简便方法

在当前的研究中，我们探索了利用甲磺酸铯作为新型双功能化学活化剂直接合成掺杂 S 的多孔碳。所获得的碳具有高比表面积（654-2264 m2/g）和高 S 含量（6.56-15.13 wt%）。此外，还研究了活化温度和甲基磺酸铯含量对碳特性的影响。在 0 °C 和 1 bar 条件下，所获得的碳化物的二氧化碳吸收量为 3.58-4.76 mmol/g。讨论了质地特性和 S 掺杂对二氧化碳吸附性能的影响。
