An operational advantage that enables the deployment of technologies for the valorization of CO2 can be achieved through the integration of the capture and conversion technologies. In that perspective, switchable polarity solvents (SPS) were assessed as re-usable capture-electrolyte media for the electrochemical production of syngas at low temperatures and pressures. A polymer electrolyte membrane cell was used to liberate captured CO2 gas in proximity to the cathode without the addition of CO2 gas. Due to the proximate location of release, the produced syngas had minimal CO2 dilution with H2 : CO ratios between 2 to 4. For the first time captured CO2 has been reduced to CO with conversions and yields over 70% and at current densities over 100 mA cm−2.

从可转换极性溶剂中捕获的CO 2电化学生产合成气

通过集成捕获和转化技术,可以实现可部署用于CO 2增值技术的运营优势。从这个角度出发,可转换极性溶剂(SPS)被评估为可在低温和低压下电化学生产合成气的可回收捕获电解质介质。一种聚合物电解质膜细胞被用来释放捕获的CO 2在接近阴极气体不添加CO的2气体。由于靠近释放位置,因此生成的合成气的CO 2稀释度极低,H 2  :CO比率为2至4。这是首次捕获的CO 2在转化率和电流密度超过100 mA cm -2时,已被转化为一氧化碳,收率超过70%。
