“…Figure 1 shows the XRD patterns of the Z-stir-(8 h) and the ZIF-8 samples synthesized with a different treatment time with ultrasound. The characteristic peaks of the ZIF-8 structure are similar to those reported in other work [1,4,15,16,39,[45][46][47][48]. In particular, the diffraction peak (011) at 7.2°has a high intensity, indicating that ZIF-8 is highly crystalline [48].…”

Zeolitic imidazolate framework-8 (ZIF-8) is synthesized quickly at room temperature in methanol with the support of ultrasound. Porous ZnO is also prepared via the thermal treatment of ZIF-8. The photocatalytic activities of the obtained materials are demonstrated via methylene blue (MB) decomposition under UV radiation. The obtained materials are characterized by means of X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), nitrogen adsorption/desorption isotherms, UV-Vis diffuse reflectance spectra (DR-UV-Vis), and photoluminescence spectra. The results indicate that ZIF-8 and the materials obtained from ZIF-8 by heating in the air have photocatalytic activity under UV irradiation. The ZnO sample obtained by ZIF-8 calcination at 660°C for 5 h has the highest photocatalytic activity. However, the MB degradation photocatalytic efficiency of the ZnO samples is even lower than that of the ZIF-8 samples, indicating that ZIF-8 is an effective photocatalyst in the treatment of environmental pollution.

“…The authors also showed that ZIF-8 has higher photocatalytic activity than other materials. In addition, ZIF-8 is also used as a substrate to fabricate composites [8][9][10][11][12][13][14][15][16] or core-shell materials [17][18][19][20] with different elements to expand the applicability of this metal-organic framework material.…”

“…239 Additionally, plasmonic-MOF nanocomposites have promise in surface enhanced Raman spectroscopy-based sensor applications. [240][241][242][243][244][245] A magnetoelastic sensor technique was recently demonstrated, in which UiO-66-NH 2 was spray-coated onto a rhombic-shaped strip of a ferromagnetic alloy, which could be used as a wireless sensor for toluene. Similar to SAW devices, a magnetoelastic sensor operates based upon the impact of mass change on the magnetoelastic resonance frequency.…”

“…In addition, MOFs can efficiently and selectively capture analytes, including gases, and bring them near the plasmonic surface, because of their larger surface area, π–π interactions, 69 hydrophobic/hydrophilic properties, pore size, and so forth 98,99 . This enrichment ability leads to a significant improvement of the SERS performance of plasmonic platforms 100–105 . It has been shown that coating Au NPs with uniform and thin shells of MOF‐5 allowed the selective SERS detection of CO 2 in gas mixtures, 38 due to the specific adsorption of CO 2 molecules by MOF‐5, leading to a significant enhancement of the Raman signal at 1395 cm −1 .…”

Plasmonic metal‐organic frameworks are composite nanoparticles comprising plasmonic metal nanoparticles (NPs) embedded within a metal‐organic framework (MOF) matrix. As a result, not only the functionalities of the individual components are retained, but synergistic effects additionally provide improved chemical and physical properties. Recent progress in plasmonic MOFs has demonstrated the potential for nanofabrication and various nanotechnology applications. Synthetic challenges toward plasmonic MOFs have been recently addressed, resulting in new opportunities toward practical applications, such as surface‐enhanced Raman scattering, therapy, and catalysis. The impact of key parameters (thermodynamic vs. kinetic) on the synthetic pathways of plasmonic MOFs is reviewed, while providing insight into related progress toward structure‐derived applications.
