P-T-induced evolution of the local structure of family of MOFs characterized by X-ray absorption spectroscopy

We propose to exploit high pressure - high temperature (HP–HT) X-ray Absorption Spectroscopy (XAS) to explore the local atomic structure around Zr in three Metal-Organic Frameworks (MOFs), UiO-66, NU-1000 and MOF-808, in the HP and HT region. As part of the PhD project of Ms. G. Robertson, this information will be combined with HP–HT pair distribution function (PDF) results (scheduled as in house at Diamond Light Source) to deeply understand the P–T-induced microstructural changes associated with the crystalline-amorphous phase transition in MOFs.

我们提出利用高压-高温（HP-HT）X射线吸收光谱（X-ray Absorption Spectroscopy, XAS），探究三种金属有机框架（Metal-Organic Frameworks, MOFs）——UiO-66、NU-1000与MOF-808——在高压高温区域中Zr周围的局部原子结构。作为G. Robertson女士博士项目的组成部分，该信息将与高压-高温对分布函数（pair distribution function, PDF）结果（计划于钻石光源（Diamond Light Source）内部开展）相结合，以深入理解MOFs中由压力-温度（P-T）诱导、与晶态-非晶态相变相关的微观结构变化。
