The photocatalytic direct conversion of carbon dioxide (CO) from flue gas into high-value products is regarded as one of the most promising approaches to achieving carbon neutrality. Nevertheless, this direct conversion process encounters significant challenges, primarily due to practical limitations such as low CO concentrations and the presence of interfering substances. Porous crystalline framework materials exhibit considerable potential in flue gas conversion, attributed to their robust CO capture capabilities, well-defined and tunable structures, high specific surface areas, and plentiful catalytic sites. This review highlights strategies to improve the capture and activation of low-concentration CO by porous crystalline materials including functionalization of organic ligands, creation of open metal sites (OMSs) and Lewis basic sites (LBSs), as well as strategies to improve the catalytic activity of flue gas reforming, which encompasses anchoring of catalytic sites to the skeleton, fabricating composites, and preparing derived materials. The review aims to provide insights and guidance for the design and development of efficient catalysts specifically tailored for flue gas reforming.
将烟道气中的二氧化碳（CO₂）光催化直接转化为高价值产品被视为实现碳中和最具前景的方法之一。然而，这种直接转化过程面临重大挑战，主要是由于实际限制，如CO₂浓度低和存在干扰物质。多孔晶体骨架材料在烟道气转化中显示出相当大的潜力，这归因于它们强大的CO₂捕获能力、明确且可调的结构、高比表面积和丰富的催化位点。本综述重点介绍了通过多孔晶体材料改善低浓度CO₂捕获和活化的策略，包括有机配体的功能化、开放金属位点（OMS）和路易斯碱位点（LBS）的创建，以及提高烟道气重整催化活性的策略，其中包括将催化位点锚定到骨架上、制备复合材料和制备衍生材料。本综述旨在为专门针对烟道气重整设计和开发高效催化剂提供见解和指导。
