In the past two decades, great progress has been made in the aspects of fabrication and application of ordered mesoporous metal oxides. Ordered mesoporous metal oxides have attracted more and more attention due to their large surface areas and pore volumes, unblocked pore structure, and good thermal stabilities. Compared with non-porous metal oxides, the most prominent feature is their ability to interact with molecules not only on their outer surface but also on the large internal surfaces of the material, providing more accessible active sites for the reactants. This review carefully describes the characteristics, classification and synthesis of ordered mesoporous metal oxides in detail. Besides, it also summarizes the catalytic application of ordered mesoporous metal oxides in the field of carbon dioxide conversion and resource utilization, which provides prospective viewpoints to reduce the emission of greenhouse gas and the inhibition of global warming. Although the scope of current review is mainly limited to the ordered mesoporous metal oxides and their application in the field of CO₂ catalytic conversion via heterogeneous catalysis processes, we believe that it will provide new insights and viewpoints to the further development of heterogeneous catalytic materials.
在过去二十年中，有序介孔金属氧化物的制备和应用方面取得了巨大进展。有序介孔金属氧化物因其大的表面积和孔体积、畅通的孔结构以及良好的热稳定性而受到越来越多的关注。与无孔金属氧化物相比，其最突出的特点是不仅能够在其外表面而且能够在材料的大的内表面与分子相互作用，为反应物提供更多可及的活性位点。本综述详细描述了有序介孔金属氧化物的特性、分类和合成。此外，还总结了有序介孔金属氧化物在二氧化碳转化和资源利用领域的催化应用，为减少温室气体排放和抑制全球变暖提供了前瞻性观点。尽管当前综述的范围主要限于有序介孔金属氧化物及其在通过多相催化过程进行的CO₂催化转化领域的应用，但我们相信它将为多相催化材料的进一步发展提供新的见解和观点。
