As a major greenhouse gas, the continuous increase of carbon dioxide (CO₂) in the atmosphere has caused serious environmental problems, although CO₂ is also an abundant, inexpensive, and nontoxic carbon source. Here, we use metal-organic framework (MOF) with highly ordered hierarchical structure as adsorbent and catalyst for chemical fixation of CO₂ at atmospheric pressure, and the CO₂ can be converted to the formate in excellent yields. Meanwhile, we have successfully integrated highly ordered macroporous and mesoporous structures into MOFs, and the macro-, meso-, and microporous structures have all been presented in one framework. Based on the unique hierarchical pores, high surface area (592 m²/g), and high CO₂ adsorption capacity (49.51 cm³/g), the ordered macroporous-mesoporous MOFs possess high activity for chemical fixation of CO₂ (yield of 77%). These results provide a promising route of chemical CO₂ fixation through MOF materials.

作为一种主要的温室气体，大气中二氧化碳(CO ₂ )的不断增加已经造成了严重的环境问题，尽管CO ₂也是一种丰富、廉价且无毒的碳源。在这里，我们使用具有高度有序分级结构的金属有机骨架（MOF）作为吸附剂和催化剂，在常压下化学固定CO ₂ ，​​并且CO ₂可以以优异的收率转化为甲酸盐。同时，我们成功地将高度有序的大孔和介孔结构集成到MOF中，并且宏观、介孔和微孔结构都呈现在一个框架中。基于独特的分级孔、高比表面积（592 m ² /g）和高CO ₂吸附容量（49.51 cm ³ /g），有序大孔-介孔MOFs具有高的CO ₂化学固定活性（产率77%）。这些结果提供了通过MOF材料化学固定CO ₂的有前景的途径。
