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.

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 ...

The morphology and components of the ZIF-8 were characterized by scanning electron microscopy (SEM), powder X-ray diffraction spectroscopy (PXRD), thermogravimetric analysis (TGA), Fourier-transform infrared spectroscopy (FT-IR) and zeta potential analysis.

In this study, ZIF-8 with a rhombic dodecahedron structure was prepared by a hydrothermal method. Then La (OH)3, was successfully loaded onto the ZIF-8 by an immersion deposition method, to...

2024年2月1日 · The synthesis process entails immersing an annealed zeolitic imidazolate framework-8 (ZIF-8), prepared at 900 °C as a carbon source, into an IrCl3 solution, followed by a calcination-reduction treatment at 400 °C under a H2/Ar atmosphere.

A Zeolitic imidazolate framework-8 (ZIF-8) was synthesized by the solvothermal method of zinc nitrate hexahydrate and 2-methylimidazole in DMF to remove...

2024年9月5日 · The Ir-ZIF-8, a functional metal–organic framework (MOF), exhibited the AIECL phenomenon via the spatial domain-limiting effect of encapsulating Ir(ppy) 3 into the mesopores of ZIF-8, while the porosity and highly ordered topological structure of ZIF-8 effectively limited the molecular motion of Ir(ppy) 3. CRISPR-Cas12a was employed to ...

2024年5月16日 · Here, we systematically investigate ZIF-8 vibrational spectra by combining experimental IR spectroscopy and first-principles molecular dynamics simulations, focusing on assigning peaks and elucidating the spectroscopic signals of putative defects present in …

3 天之前 · 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).

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。
