powder X-ray diffraction (PXRD), IR- and 1H-NMR spectroscopy, thermal gravimetric analysis (TGA) and N2 sorption were employed. The valence state of the Ru-sites were studied by X-ray absorption spectroscopy (XAS). The chosen precursors for CSA and optimized synthesis, work-up and activation...
Characterization through powder X-ray diffraction (PXRD), N2-adsorption, scanning electron microscopy (SEM), thermogravimetric analysis (TGA), and Fourier transform infrared (FT-IR) spectroscopy confirmed the formation of a MOF with the HKUST-1 topology, albeit with lower porosity compared to neat ...
In addition to PXRD, their adsorptive performance has to be evaluated. C2H2 adsorption isotherm at 20 °C demonstrates that the total uptake for HKUST-1 after the water stability experiment is 1.01 mmol/g which is 90 % less than the total uptake (8.88 mmol/g) found in the pristine HKUST-...
[0065](6)将实施例1～4制备得到的新型复合材料HKUST‑1@PQ分别标注为HKUST‑1@PQ‑1、HKUST‑1@PQ‑2、HKUST‑1@PQ‑3、HKUST‑1@PQ‑4,并对上述新型复合材料进行PXRD测试,测试结果如图6所示。 [0066]由图6可以看出,HKUST‑1@PQ‑1、HKUST‑1@PQ‑2、HKUST‑1@PQ‑3、HKUST‑...
In this work, the HKUST-1 and Co-MOF-74 powders were shaped with polyvinyl alcohol as a binder, and the impact on the crystal structures of HKUST-1 and Co-MOF-74 in the shaping process was characterized by PXRD. The adsorption isotherms of N2, Xe and Kr on powder and pellets were ...

found that the reduced intensity or even missing first reflex in the PXRD pattern is in relation to the loss of the fcc crystal structure of HKUST-1.45 Through our CH elemental analysis (Table S2†) we know that solvent molecules are in our MOF samples and it would be possible that mec...
SEM, PXRD and FTIR The surface morphology of the modifiers was investigated using SEM. Fig. 1 depicts the SEM images of the synthesized HKUST-1, CuO nanoparticles and the composite CuO@HKUST-1. The SEM micrograph of HKUST-1 (Fig. 1A) reveals that the synthesized MOF products have octahedral...
