摘要:

以化石能源為主體的能源消耗不僅造成嚴重的大氣污染，還產生大量的CO2，加劇了氣候惡化。“減污降碳”成為全球綠色高質量發展的重大戰略需求。其中，將CO2催化轉化為高附加值碳基化合物成為當前能源與環境領域研究的熱點。目前，CO2催化還原的技術主要有熱催化、光催化、電催化、光熱催化和光電催化等。其中，光熱耦合的光驅動光熱協同催化技術不但克服了單一光/熱催化技術的不足，而且能充分發揮二者的優勢，在低（無）能耗的條件下實現高效高選擇性催化還原CO2制備碳基化合物，是一種理想的催化還原路徑。針對光熱催化的分類、機理以及光熱催化還原CO2催化劑的優化設計分別做出了概述，并論述了光熱催化還原CO2的工業應用以及現存的問題，最后對光熱催化還原CO2技術的未來發展進行了展望。

Abstract:

he energy consumption dominated by fossil fuels not only causes serious air pollution, but also generates a large amount of CO2, exacerbating climate degradation. Reducing pollution and carbon emissions has become a major strategic requirement for global green and high�瞦uality development. Among them, the utilization of CO2 resources can not only reduce environmental pollution, but also generate the carbon�瞓ased products by its reduction, which are often important chemical intermediates with great application value, therefore, the preparation of carbon�瞓ased products by CO2 reduction has become a hotspot of current research in the field of energy and environment. At present, CO2 catalytic reduction methods mainly include thermal catalysis, photocatalysis, electrocatalysis, photothermal catalysis and photoelectrocatalysis, etc. Among them, the photothermal coupling of light�瞕riven photothermal synergistic catalytic technology not only overcomes the deficiencies of a single catalytic technology, but also gives full play to the advantages of the two, and realizes the preparation of carbon�瞓ased compounds from CO2 reduction with high efficiency and selectivity under the condition of low (no) energy consumption, which is an ideal reduction pathway. The paper provides an overview of the classification, mechanism, and optimization design of photothermal catalysis for CO2 reduction and also discusses the industrial application and existing problems of photothermal catalysis for CO2 reduction. Finally, the future development of photothermal catalysis for CO2 reduction technology is discussed.
