本レビューは、CO2回収技術を燃焼段階に基づき予燃焼、燃焼中、燃焼後に分類し、後燃焼回収における吸収、吸着、膜分離の各手法を詳述。性能向上のための機能化や複合システムなどの戦略を紹介し、大規模展開にはコスト・エネルギー消費・材料安定性の課題があると指摘。将来は低コストで効率的かつ堅牢な材料とプロセス開発が重要である。
English
This review systematically classifies CO2 capture technologies into pre-combustion, combustion-based, and post-combustion routes, with a focus on post-combustion methods including absorption, adsorption, and membrane separation. It highlights strategies like functionalization and composite systems to enhance performance. Despite progress, large-scale deployment faces challenges in cost, energy consumption, and material stability. Future research should prioritize low-cost, energy-efficient, and robust solutions for net-zero emissions.

📄 Abstract（原文）
The rapid increase in atmospheric CO2 concentration has made carbon capture an essential strategy for mitigating climate change. This review systematically summarizes CO2 capture technologies following the complete process chain. First, three major routes based on combustion stages are introduced: pre-combustion (e.g., coal gasification, biomass co-firing), combustion-based (oxy-fuel combustion and chemical looping combustion), and post-combustion capture. For post-combustion capture, which is the most widely applicable to existing emission sources, three core separation methods are further elaborated: absorption (amine blends, ionic liquids, deep eutectic solvents), adsorption (zeolites, activated carbon, MOFs, COFs, solid amine sorbents), and membrane separation (polymeric, inorganic, and mixed matrix membranes). Key strategies for performance enhancement—such as functionalization, pore engineering, and composite systems—are highlighted. Despite significant advances, large-scale deployment remains challenged by high costs, high energy consumption, and inadequate material stability. Future research should prioritize low-cost, energy-efficient, and robust capture materials and processes to enable net-zero and negative carbon emissions.
