本レビューは、再生可能エネルギー駆動のCO2回収・利用（CCU）について、材料とプロセスの関係を軸に体系的に整理する。ゼオライト、MOF、COF、イオン液体、深共晶溶媒などの吸着・吸収材料の熱力学、選択性、再生エネルギー損失を論じ、光触媒・熱化学的転換プロセスを評価する。特に吸着と触媒変換を直接結合する統合型回収・転換（ICCU）を、エネルギー・分離コスト削減の有望戦略として位置づける。材料不安定性、物質移動制約、再生・水素製造の高エネルギー需要、技術経済性がスケールアップの障壁だと指摘する。
English
This review systematically examines renewable-energy-driven CO2 capture and utilization (CCU), focusing on material–process relationships. It assesses adsorption/absorption systems (zeolites, MOFs, COFs, ionic liquids, deep eutectic solvents) alongside photocatalytic and thermochemical conversion routes. Integrated capture and conversion (ICCU) is highlighted as an emerging strategy to cut energy and separation costs. Scale-up barriers include material instability, mass-transfer limits, high regeneration and hydrogen energy demands, and techno-economic concerns.

📄 Abstract（原文）
Rising atmospheric CO 2 concentrations demand sustainable carbon management strategies. Renewable energy‐driven CO 2 capture and utilization (CCU) offers a promising route to emission mitigation and sustainable fuel synthesis. This review systematically examines green CO 2 capture techniques, focusing on the material–process relationships that govern performance. Adsorption and absorption systems, including zeolites, metal–organic frameworks (MOFs), covalent organic frameworks (COFs), nanostructured sorbents, ionic liquids, and deep eutectic solvents (DESs), are discussed with attention to adsorption thermodynamics, sorbent–CO 2 interactions, selectivity, and regeneration energy penalties. Renewable CO 2 conversion processes, including photocatalytic and thermochemical approaches, are assessed. Integrated capture and conversion (ICCU) systems are highlighted as an emerging strategy that directly couples adsorption and catalytic transformation to reduce energy and separation costs. Despite notable progress, scale‐up remains hampered by material instability, mass‐transfer limitations, high energy demands for regeneration and hydrogen production, and techno‐economic concerns. Unlike reviews that address capture, conversion, or ICCU in isolation, this review offers an integrated materials‐to‐process perspective linking green capture materials, renewable energy inputs, conversion pathways, and fuel synthesis, with particular attention to the transition from separate to integrated capture–conversion processes. It emphasizes rational capture‐material design, renewable energy integration, and catalytic process optimization to advance CO 2 ‐to‐fuel technologies toward industrial viability and a circular economy.
