SO₂ emissions not only affect local air quality but can also contribute to other environmental issues. Developing low-cost and robust adsorbents with high uptake and selectivity is needed to reduce SO₂ emissions. Here, we show the SO₂ adsorption–desorption capacity of carbon microfibers (CMFs) at 298 K. CMFs showed a reversible SO₂ uptake capacity (5 mmol g⁻¹), cyclability over ten adsorption cycles with fast kinetics and good selectivity towards SO₂/CO₂ at low-pressure values. Additionally, CMFs’ photoluminescence response to SO₂ and CO₂ was evaluated.

使用聚丙烯腈合成的碳微纤维 (CMF) 捕获和检测 SO2

SO ₂排放不仅影响当地空气质量，还会导致其他环境问题。_{为了减少 SO 2}排放，需要开发具有高吸收率和选择性的低成本、稳健的吸附剂。在这里，我们展示了碳微纤维（CMF）在 298 K 下的 SO ₂吸附-解吸能力。CMF 表现出可逆的 SO ₂吸收能力（5 mmol g ^-1），可循环超过十个吸附周期，具有快速动力学和对 SO 的良好选择性₂ /CO ₂处于低压值。此外，还评估了CMF对SO ₂和CO _{2的光致发光响应。}
