Application of MOFs materials in catalysts for CO2 hydrogenation

摘要:

CO2作为最主要的温室气体，大量排放引发了全球变暖等一系列环境问题。通过化学过程将CO2转化为具有价值的产品对于应对气候变化具有重要意义。甲醇既是一种高能量燃料又是重要化工中间体，利用CO2加氢合成甲醇是实现CO2循环利用的切实可行的途径。但目前CO2加氢制甲醇催化剂存在反应选择性低、CO2转化率低、合成速率低等一系列问题，因此，开发高效、高选择性的催化剂是实现CO2加氢制甲醇工业化应用的关键。近年来，金属有机骨架（MOFs）材料由于其结构多样性、设计灵活性的特点在催化领域引起了广泛关注，应用于CO2加氢合成甲醇催化剂合成，可以有效提高催化性能。本文对该类催化剂的优势、合成方法及其研究进展进行了评述，并对其应用的挑战和前景进行了讨论。

Abstract:

As one of the major greenhouse gases, CO2 has caused a series of environmental problems, such as global warming. CO2 conversion to valuable products is of great significance to alleviating global climate issues. Methanol is not only a high energy fuel but an important chemical intermediate. CO2 hydrogenation to methanol is a feasible way to realize CO2 recycling. However, at present, there are a series of problems such as low selectivity, low CO2 conversion rate and low methanol synthesis rate. Thus, the development of efficient and highly selective catalysts is critical to realize the industrial application of CO2 hydrogenation to methanol. In recent years, metal-organic framework (MOFs) materials have attracted extensive attention in the field of catalysis due to their structural diversity and design flexibility. In this paper, we reviewed the advantages, synthesis methods and research progress of MOFs catalysts in the field of CO2 hydrogenation to methanol. Furthermore, the challenges and prospects of the application of MOFs catalysts in this field were also discussed.
