材料的缺陷控制既是过去和现用材料的主要问题，也是现在和将来新材料的研制开发的关键。对于多孔材料而言，其晶体缺陷更是与其多孔性直接相关，在晶体缺陷存在的情况下，孔形状、孔径以及孔道环境都会受到显著影响。金属有机框架材料被认为是实现低能耗气体存储与分离技术的理想选择。然而，晶体缺陷对于金属有机框架材料的吸附性能影响是一把“双刃剑”，晶体缺陷的存在，既可以提高孔洞率和提供吸附位点，但同时也破坏了孔道的规整性，其关键问题在于缺陷的控制，如何控制金属有机框架材料中缺陷将成为提高其性能的新手段和新的增长点。尽管科学家们逐步意识到晶体缺陷对于金属有机框架材料的性能有着重要影响，目前仍难以有效实现系统调控金属有机框架材料中的晶体缺陷进而实现性能优化。本项目拟通过构筑/修补晶体缺陷的方式，可控地调节晶体缺陷，进而优化金属有机框架材料的储气/分离性能，期望为金属有机框架材料的发展带来新的推动力。

Material defect control is not only the main problem of past and current materials, but also the key to the development of new materials now and in the future. For porous materials, the crystal defects are directly related to their porosity. In the presence of crystal defects, the pore shape, pore size, and pore environment will be significantly affected. Metal-organic framework materials are considered to be ideal choices for low-energy gas storage and separation technology. However, the influence of crystal defects on the adsorption performance of metal-organic framework materials is a "double-edged sword". The presence of crystal defects can not only improve the porosity and provide adsorption sites, but also destroy the regularity of the pores. Its key The problem lies in the control of defects. How to control the defects in metal-organic framework materials will become a new method and a new growth point to improve their performance. Although scientists have gradually realized that crystal defects have an important impact on the performance of metal organic framework materials, it is still difficult to effectively control the crystal defects in metal organic framework materials to achieve performance optimization. This project intends to control the crystal defects by constructing / repairing the crystal defects, thereby optimizing the gas storage / separation performance of the metal organic framework materials, and hopes to bring new impetus to the development of metal organic framework materials.
