摘要
以化石能源为主体的能源消耗不仅造成严重的大气污染,还产生大量的CO_(2),加剧了气候恶化。“减污降碳”成为全球绿色高质量发展的重大战略需求。其中,将CO_(2)催化转化为高附加值碳基化合物成为当前能源与环境领域研究的热点。目前,CO_(2)催化还原的技术主要有热催化、光催化、电催化、光热催化和光电催化等。其中,光热耦合的光驱动光热协同催化技术不但克服了单一光/热催化技术的不足,而且能充分发挥二者的优势,在低(无)能耗的条件下实现高效高选择性催化还原CO_(2)制备碳基化合物,是一种理想的催化还原路径。针对光热催化的分类、机理以及光热催化还原CO_(2)催化剂的优化设计分别做出了概述,并论述了光热催化还原CO_(2)的工业应用以及现存的问题,最后对光热催化还原CO_(2)技术的未来发展进行了展望。
The energy consumption dominated by fossil fuels not only causes serious air pollution,but also generates a large amount of CO_(2),exacerbating climate degradation.Reducing pollution and carbon emissions has become a major strategic requirement for global green and high-quality development.Among them,the utilization of CO_(2) resources can not only reduce environmental pollution,but also generate the carbon-based products by its reduction,which are often important chemical intermediates with great application value,therefore,the preparation of carbon-based products by CO_(2) reduction has become a hotspot of current research in the field of energy and environment.At present,CO_(2) catalytic reduction methods mainly include thermal catalysis,photocatalysis,electrocatalysis,photothermal catalysis and photoelectrocatalysis,etc.Among them,the photothermal coupling of light-driven 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-based compounds from CO_(2) 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 CO_(2) reduction and also discusses the industrial application and existing problems of photothermal catalysis for CO_(2) reduction.Finally,the future development of photothermal catalysis for CO_(2) reduction technology is discussed.
