MOF-5 began to decompose above 380°C, which is much higher than the reaction temperatures of the cycloaddition reaction (90°C) and the transesterification reaction (130°C). The FTIR spectrum of...

2018年7月15日 · In this work, rod-like metal-organic framework (MOF-5) nanomaterial was synthesized by a solvothermal method and applied to efficiently adsorb U (VI) from aqueous solutions.

2021年10月5日 · The structures and properties of MOF-5 and Ag@MOF-5 were characterized by X-ray powder diffraction (XRD), scanning electron microscope (SEM), high-resolution transmission electron microscope and energy spectrum (HR-TEM&EDS), infrared spectrum (FTIR) and thermal gravimetric analysis (TGA).

The MOF-5 samples were synthesized using the solvothermal reaction method, and successful synthesis was confirmed with x-ray diffraction (XRD), microscopy, Fourier transform infrared spectroscopy...

MOF-5, also called as IRMOF-1, is a zinc based metal-organic framework that is made up of [Zn 4 O] 6+ inorganic moiety as the vertex and benzene dicarboxylic acid as the bifunctional bridging ligand of the crystal (Civalleri et al., 2006). MOF-5 crystal has a symmetric fcc lattice structure (Zhou and Yildirim, 2008).

As demonstrated in the FTIR of the crystal MOF-5 in Figure 2, the strong peaks at the point 3500-3200 cm −1 was caused by the O-H of adsorbed water. There are two strong absorption peaks in about 1384cm −1 and 1657cm −1,which belong to the stretching vibration peaks of -C=O in …

2018年6月2日 · 利用X射线衍射仪 (XRD)、扫描电子显微镜 (SEM)、傅里叶红外光谱仪 (FTIR)以及热重分析仪 (TG)等仪器对MOF-5晶体进行了表征。 研究了不同合成方法对其结构、形貌及热稳定性等性质的影响。

在拉曼，FTIR，DR-UV和XRD测量的基础上，讨论了基于Zn 4 O的MOF在潮湿或含水环境下有限的稳定性以及激发机理的现有问题。 本文表明，分散在水中的MOF-5产生相对稳定的新相MOF-5W，该相缓慢降解为MOF-5W和MOF-5W与对苯二甲酸锌二水合物（ZTDH）的混合物。

2020年6月6日 · FTIR analysis shown that the terephthalic acid is completely protonated, and the Zn2+ and the carboxyl group are formed by the coordination of the multi-tooth bridge in the crystal of MOF-5. Then the structure activity relationship of the crystal MOF-5 synthesis, microstructural, thermal stability and N2 adsorption property were further studied.

2019年9月16日 · Herein, MOF-5 was synthesized by the solvothermal method and direct addition method, and characterized by Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), Fourier Transform Infrared Spectrometer (FTIR), Thermogravimetric Analysis (TG), Brunauer–Emmett–Teller (BET), and Dynamic Light Scattering (DLS), respectively.
