CO2回収に用いられる主要な化学システム（アミン、炭酸塩、カルシウムループ、イオン液体、多孔質固体）を、結合強度・選択性・作業容量・再生エネルギーという共通枠組みで比較した総説。ゼオライトのカチオン設計や疎水性制御、成形体拡散に関する最近の進展を重点的に整理。回収と下流変換を一体化する反応性（二機能性）吸着材の動向も論じ、選択性向上と再生エネルギー増大のトレードオフを設計課題として提示する。
English
A critical review of the main chemical systems for CO2 capture—amines, carbonates, calcium looping, ionic liquids, and porous solids—compared within a common framework of binding strength, selectivity, working capacity, and regeneration energy. It highlights zeolite advances in cation engineering, hydrophobicity control, and shaped-body diffusion, and surveys reactive dual-functional sorbents that couple capture with downstream conversion. A recurring design tension—higher affinity and selectivity raising regeneration energy—frames future materials and process directions.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
CCUSは日本のGX実現に向けた重要技術の一つであり、特に反応性吸着材による回収・変換一体化は産業脱炭素のコスト低減に寄与しうる。ただし本稿は基礎化学のレビューであり、SSBJ・有報・投資家対応といった開示文脈との直接的な接点は乏しい。日本の化学・素材メーカーの技術戦略を考える上での参考資料として位置づけられる。
In the global GX context
CO2 capture chemistry underpins CCUS, a pillar of many national decarbonization plans and increasingly relevant to transition finance and industrial decarbonization roadmaps. While the paper is a materials-science review rather than a disclosure study, it informs the technological assumptions behind corporate net-zero pathways and the credibility of CCUS-based abatement claims under frameworks like TCFD/ISSB.

📄 Abstract（原文）
Carbon dioxide capture is central to any credible strategy for reducing anthropogenic emissions, and the chemistry behind it spans a wide range of materials and mechanisms. This feature article provides a critical review of the main classes of chemical systems used for CO2 capture, including aqueous and supported amines, carbonate-based sorbents, high-temperature calcium looping materials, ionic liquids, and crystalline porous solids. These systems are considered within a common framework that balances binding strength, selectivity, working capacity, and regeneration energy. Particular focus is given to zeolites, whose well-defined microporous structures, tunable extra-framework cations, and established industrial use make them versatile candidates for selective CO2 physisorption. We highlight recent progress in cation engineering, hydrophobicity control, and shaped-body diffusion, including contributions from our own work and related studies from other groups. The article also discusses the rapidly growing field of reactive, or dual-functional sorbents, where CO2 capture is coupled directly with downstream conversion, narrowing the gap between capture and utilisation. Across these material families, a recurring design challenge emerges: increasing affinity and selectivity often raises the energy required for regeneration. We conclude by outlining the materials design principles and process-level considerations most likely to guide future advances in efficient and selective CO2 capture.
