摘　　要：简要介绍了二维和三维COFs的结构,重点介绍了COFs作为储氢材料的研究现状和提高其储氢性能的改性方法,并对COFs在储氢方面存在的不足和未来的研究方向作出了总结与展望。Hydrogen storage is the key issue for the utilization of hydrogen energy. Covalent organic frameworks （COFs） are porous networks, which are entirely made from light elements（such as C, H, O, B, etc. ）through strong covalent bonds. Due to their large surface areas, low density, high thermal stability and well-controlled structures, COFs have been attracted intensive attention as a kind of promising porous materials for hydrogen storage. The recent progress in structures and methods for synthesis of COFs was reviewed. The hydrogen storage of recently reported COFs and the approaches for improvement of hydrogen adsorption performance of COFs were also lined out. Finally, our conclusions and outlook on the current research status, drawbacks and future direction of COFs as hydrogen storage media were provided.
