本論文は、CO2回収技術（燃焼前、燃焼後、直接空気回収）と変換技術（熱触媒、電解、光触媒、バイオ変換）を体系的にレビューし、統合的キャプチャー・変換技術の可能性と課題を比較評価している。化学吸収が主流だが高エネルギー消費、物理吸着は高圧下で有効、熱触媒は水素供給に依存、電解・光触媒は将来性がある。
English
This review systematically compares CO2 capture (pre-combustion, post-combustion, direct air capture) and conversion technologies (thermocatalysis, electrocatalysis, photocatalysis, bioconversion). It evaluates principles, energy consumption, efficiency, economic viability, and industrialization stage. Key findings: chemical absorption is mainstream but energy-intensive; physical adsorption works under high pressure; thermocatalysis depends on hydrogen; electrocatalysis and photocatalysis show promise; integrated capture-conversion may transform energy use but faces material stability issues.

📄 Abstract（原文）
Large-scale carbon dioxide emissions are the primary cause of global warming: to achieve the 'dual carbon' targets, it is essential to develop carbon dioxide capture and conversion technologies and to advance their application and development. This paper provides a systematic review of the mainstream CO₂ separation technologies currently in use, including pre-combustion capture, post-combustion capture and direct air capture, as well as the technical principles, maturity and key bottlenecks of pathways for converting CO₂ into resources through thermocatalysis, electrocatalysis, photocatalysis and bioconversion. It also focuses on the cutting-edge coupled application technology of integrated capture and conversion. On this basis, a comparison is conducted across multiple aspects, including principles, energy consumption, efficiency, economic viability and the stage of industrialisation. The results indicate that chemical absorption is the mainstream method for post-combustion capture, but it has high energy consumption; physical adsorption offers significant advantages under the high-pressure conditions of pre-combustion capture; thermal catalytic technology is highly dependent on hydrogen supply; electrocatalytic and photocatalytic technologies hold great potential; and integrated capture-conversion technology is expected to transform traditional energy consumption patterns, although material stability remains a challenge.
