Metal-organic frameworks (MOFs) materials constructed by the coordination chemistry of metal ions and organic ligands are important members of the crystalline materials family. Owing to their exceptional properties, for example, high porosity, tunable pore size, and large surface area, MOFs have been applied in several fields such as gas or liquid adsorbents, sensors, batteries, and supercapacitors. However, poor conductivity and low stability hamper their potential applications in several attractive fields such as energy and gas storage. The integration of MOFs with carbon nanotubes (CNTs), a well-established carbon allotrope that exhibits high conductivity and stability, has been proposed as an efficient strategy to overcome such limitations. By combining the advantages of MOFs and CNTs, a wide variety of composites can be prepared with properties superior to their parent materials. This review provides a comprehensive summary of the preparation of CNT@MOF composites and focuses on their recent applications in several important fields, such as water purification, gas storage and separation, sensing, electrocatalysis, and energy storage (supercapacitors and batteries). Future challenges and prospects for CNT@MOF composites are also discussed.
金属-有机骨架（MOFs）材料是由金属离子和有机配体的配位化学构建而成的，是晶体材料家族中的重要成员。由于其独特的性质，例如高孔隙率、可调节的孔径和大表面积，MOFs 已应用于气体或液体吸附剂、传感器、电池和超级电容器等多个领域。然而，导电性差和稳定性低阻碍了它们在能源和气体储存等几个有吸引力的领域的潜在应用。将 MOFs 与碳纳米管（CNTs）结合，是克服这些限制的一种有效策略，CNTs 是一种性能稳定、导电性高的成熟碳同素异形体。通过结合 MOFs 和 CNTs 的优势，可以制备出具有优于母体材料性能的多种复合材料。本综述全面总结了 CNT@MOF 复合材料的制备，并重点介绍了它们在水净化、气体储存和分离、传感、电催化以及储能（超级电容器和电池）等几个重要领域的最新应用。还讨论了 CNT@MOF 复合材料未来的挑战和前景。
