In order to reduce the fire risk of rigid polyurethane foams (RPUF), three kinds of zeolitic imidazolate frameworks (ZIFs) were prepared. The results of Fourier transform infrared spectroscopy...

2017年10月1日 · Zeolitic imidazolate framework (ZIF-8) has been synthesized at room temperature in aqueous medium. Their suitability as potential drug carrier for delivery of an anti-leukemia drug, 6-mercaptopurine (6-MP) is examined. 6-MP was loaded in situ into the ZIF-8 nanoparticles during synthesis.

FT-IR has been employed to validate the existence of free Co and imidazolate bonds in ZIF-67 NCs. The SEM-EDS analyses exhibited uniform aggregated hexagonal-shaped nanoparticles and the...

2022年6月20日 · The FT-IR spectrum confirmed the successful synthesis of ZIF-8 NPs (Fig. 2a). The weak bands at 3138 and 2933 cm −1 are assigned to aromatic and aliphatic C–H stretch, respectively, of the ...

2024年2月15日 · FTIR and XPS were employed to characterize the surface properties of ZIF-8 and its modification with amino-compounds. FTIR analysis provided insights into the chemical structure and functional groups, while XPS allowed for the identification and quantification of surface elemental composition and changes resulting from the amino-compound ...

In red, the FTIR spectrum of the ZIF-8/PAN composite demonstrates the incorporation of ZIF-8 crystals within the fibers, as the pronounced peaks at 1179 cm −1 and 1146 cm −1 , characteristic...

实验结果表明：NiZn-ZIF-8较ZIF-8对大分子染料有 较好的可见光光催化性能，其中NiZn-ZIF-8对罗丹明B和亚甲基蓝的光催化降解效率优于甲基橙的光催 化降解率。 关键词 ZIF -8，NiZn-ZIF-8，光催化，染料降解 The Preparation and Photocatalytic Dye …

1 天前 · The prepared ZIF-8, GO, and ZIF-8@GO materials were characterized by Fourier transform infrared spectroscopy (FT-IR) to identify the functional groups before and after dye adsorption. The FT-IR spectra were recorded in the 4000–400 cm −1 wavenumber range at a resolution of 2 cm −1 on a Nicolet spectrophotometer (model 6700).

2015年12月17日 · 同方法合成了 ZIF-8 材料， 通过 XRD、FTIR、N2 吸 附、SEM 和 TPD 等手段对所合成的 ZIF-8 材料的物 化性能进行了较为详细的表征，并选择 Knoevenagel 缩合这一合成精细化工产品的重要反应为探针反

2011年10月31日 · ZIF-8 as a promising storage material was investigated at high pressures up to ∼39 GPa by in situ FTIR spectroscopy for the first time. Structural modifications are found to be reversible in a low-pressure region but irreversible in a high-pressure region.
