2018年7月1日 · Thermo gravimetric analysis (TGA) and scanning electron microscope (SEM) were used for further physical characterization of sample S2 (chosen from the synthesized Cu-BTC samples) and the commercial Cu-BTC sample, Basolite ® C300.

2021年10月25日 · Oxidation at 90–100 °C produced 40 nm thick films in a day and over 100 nm films in a week. Although SEM-EDS analyses in TGA tests indicated that oxygen was adsorbed on the copper surface, neither XRD patterns nor Raman spectroscopy measurements showed any trace of Cu 2 O or CuO formation on the copper

2020年10月26日 · In this study, we synthesized a series of isostructural mixed-metal metal–organic frameworks (MM-MOFs) of 1,3,5-benzenetricarboxylate (BTC), M-Cu-BTC, where M = Zn 2+, Ni 2+, Co 2+, and Fe 2+ using the post …

2020年9月15日 · Thermogravimetric analysis (TGA) data are available for the majority of MOF structures. TGA experiments record mass loss in a sample, upon heating at a steady rate under a specific atmosphere. For MOFs, this usually occurs in several distinct steps, starting with desolvation at relatively low temperatures (<150 °C).

Metal complexes have been synthesized by the reaction of thiophene-2-aldehyde thiosemicarbazone with Cu (OAc) 2 and Ni (OAc) 2. The thiosemicarbazone coordinates to metal ions through the thionic...

2013年10月1日 · A crystalline porous metal–organic framework Cu 2 (BPDC) 2 (BPY) was synthesized and characterized by X-ray powder diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), thermogravimetric analysis (TGA), Fourier transform infrared (FT-IR) spectra, atomic absorption spectrophotometry (AAS), hydrogen ...

2022年9月30日 · Cu-BTC yield CO 2 adsorption at 1.7 mmol g –1 up to 5 cycles of adsorption-desorption. The Cu-BTC (Copper-1,3,5-benzene tricarboxylate) is one of the representative metal organic frameworks (MOFs) that has shown outstanding performance for carbon dioxide (CO 2) …

2012年4月27日 · CuBTC (Copper (II) benzene-1,3,5-tricarboxylate) is one of the most well characterized and widely studied metal organic framework (MOF) structures for potential use in industrial applications due to its relatively easy synthesis and excellent textural and physicochemical properties.

2018年6月14日 · The morphological characterization of Cu@Ag reveals that excess supply of Ag-based reagent produces nanostructures with enhanced core–shell diameter, increased shell thickness, and agglomeration of Ag in the bulk surface, whereas limited supply of Ag species results in nanoparticles with imperfect enveloping of Cu core—making them ...

通过扫描电子显微镜 (SEM)、X射线衍射 (XRD)、傅里叶变换红外 (FTIR)、热重分析 (TGA)和紫外-可见 (UV-Vis)光谱对所得产物进行了表征。 SEM图像显示微波法合成的颗粒为立方体，而回流法合成的颗粒为无定形材料。 XRD谱图在2θ值为17.61°、20.47°、25.34°、29.59°、43.01°处显示出强烈的衍射峰，其米勒指数为 (511)、 (442)、 (731)、 (751)和 (662)，分别。 FTIR结果显示该材料具有 (C=O、CO、OC=O和Cu-O)等官能团，紫外-可见结果显示Cu-MOF的光吸收带微波 …
