ZSM-5への低温CO2物理吸着と、誘電体バリア放電（DBD）プラズマによる再生・in situ転換を組み合わせた統合型CCUを提案。プラズマ点火により外部加熱なしでCO2が急速に脱離し、同時にCOへ転換された。総脱離率は81.4〜85.3%に達し、Arパージのみの物理脱離（約40〜47%）を大きく上回った。放電電力とAr流量が脱離・転換挙動を制御する主要因子であることを示した。
English
This study integrates low-temperature CO2 physisorption on ZSM-5 with plasma-assisted regeneration and in situ conversion in a DBD reactor. Plasma ignition rapidly released pre-adsorbed CO2 and converted it to CO without external heating, achieving 81.4–85.3% total desorption versus ~40–47% by Ar purging alone. Discharge power and Ar flow rate control desorption and conversion, demonstrating a flexible electrically driven route to integrated carbon capture and utilization.

📄 Abstract（原文）
CO 2 capture and conversion offer a promising route to reduce emissions and support a circular carbon economy. However, conventional CO 2 regeneration typically relies on temperature- or pressure-swing processes, which can limit rapid and dynamically operated capture–conversion systems. In this work, we develop an integrated CO 2 capture–desorption–conversion approach that combines low-temperature CO 2 physisorption on ZSM-5 with plasma-assisted regeneration and in situ conversion in a dielectric barrier discharge (DBD) reactor. Upon plasma ignition, pre-adsorbed CO 2 was rapidly released and simultaneously converted to CO without external heating during the plasma-assisted regeneration stage. Total CO 2 desorption fractions of 81.4–85.3% were achieved, compared with approximately 40–47% during physical desorption by Ar purging alone. CO 2 desorption and conversion were strongly dependent on adsorption temperature, discharge power, and Ar flow rate. Notably, increasing discharge power promoted CO 2 desorption but reduced CO 2 conversion, whereas increasing the Ar flow rate enhanced CO 2 conversion with only a minor influence on total desorption. In situ plasma-coupled Fourier transform infrared (FTIR) spectroscopy revealed the formation of monodentate and bidentate carbonate species during plasma exposure. Together with the transient CO 2 and CO profiles, these observations suggest two concurrent routes for CO formation: rapid gas-phase activation of desorbed CO 2 and a possible slower surface-mediated pathway involving carbonate species. These findings demonstrate the feasibility of coupling CO 2 capture, electrically driven sorbent regeneration, and conversion within a single plasma–sorbent system, offering a flexible approach to integrated carbon capture and utilization (ICCU).
