功能介孔材料与活性基元配位结构数据集

复旦大学通过同步辐射光源下的 X 射线光电子能谱分析(XPS)、X 射线吸收近边光谱 (EANES)、X 射线吸收精细结构光谱(EXAFS)等技术探究活性基元在曲率界面上纳米配位作用机制，建立功能介孔材料与活性基元配位结构数据集，阐述了不同金属-无机、金属-有机间在受限空间内三维曲率平面上的特有的纳米配位规律，以及孔道形状、尺寸、取向、孔壁厚度、晶化程度等对纳米配位作用的影响。Fudan University investigated the nanoscale coordination mechanism of active moieties on curved interfaces using techniques including X-ray photoelectron spectroscopy (XPS), X-ray absorption near-edge structure spectroscopy (XANES), and extended X-ray absorption fine structure spectroscopy (EXAFS) under synchrotron radiation. The study established a dataset of coordination structures between functional mesoporous materials and active moieties, elucidated the unique nanoscale coordination rules of different metal-inorganic and metal-organic systems on three-dimensional curved planes within confined spaces, and revealed the effects of factors such as pore shape, size, orientation, pore wall thickness, and crystallinity on nanoscale coordination interactions.
