“…The crystalline structure of the synthesized ZIF-8 nanoparticles was investigated by XRD analysis as demonstrated in Figure 2. It can be found that the characteristic diffraction peaks of ZIF-8 at 2θ = 7.24 • [18,26,28,29,[32][33][34]. The result indicated that the ZIF-8 nanoparticle has formed a favorable crystal structure which has great potential to improve the mechanical support and structural stability of the PVA/starch blend films.…”

ZIF-8 nanoparticle-doped polyvinyl alcohol (PVA)-S-MC films were prepared via casting method. The effect of different concentrations of ZIF-8 on the physical properties and structural characterization of the films were investigated. The results indicated that ZIF-8 could increase the water resistance and mechanical property of the membrane. Through FTIR, scanning electron microscope (SEM), atomic force microscope (AFM), and TGA analysis, it was found that ZIF-8 changed the phenomenon of macromolecule agglomeration and improved the thermal stability of the membrane. The breathable behavior of the film was also studied through oxygen permeability and water vapor permeability analysis. The result illustrated that the breathability of the film improved significantly by adding ZIF-8. The maximum reached when the weight ratio of ZIF-8 was 0.01 wt %. The property expands the application of PVA/starch blend film in the postharvest technology of fruits and vegetables.

“…[ 40,41 ] The XPS spectra of Au 4f and Zn 2p as shown in Figure 1o,p. [ 42,43 ] Comparing with the XPS spectra of HZIF@TCPP‐Fe (Figure S11, Supporting Information), the appearance of peak at 714.8 eV indicates the successful embedding of Fe(III). The mole ratio of Fe in HZIF@TCPP‐Fe and HZIF@TCPP‐Fe/Fe is about 1/1.5 calculated by the result of inductively coupled plasma mass spectrometry (ICP‐MS) (Table S1, Supporting Information).…”

“…Another valid approach to reduce charge recombination rate and improve MOFs photocatalytic performance is based on their coupling with semiconductor nanoparticles, such as TiO 2 , ZnO, CdS, C 3 N 4 [255]. Cu(II)-porphyrin and TiO 2 nanoparticles into MOF structure (PCN-224(Cu)) leads to a marked improvement of light-harvesting features and promotes separation of photogenerated charges, reaching superior photocatalytic performance for CO 2 reduction [219,256]. Also, composites or heterostructures of titanium oxide or titanate fibers and MOFs, such as TiO 2 @NH 2 -MIL-88B(Fe), disclose high photocatalytic activity [257][258][259].…”

Solar radiation is becoming increasingly appreciated because of its influence on living matter and the feasibility of its application for a variety of purposes. It is an available and everlasting natural source of energy, rapidly gaining ground as a supplement and alternative to the nonrenewable energy feedstock. Actually, an increasing interest is involved in the development of efficient materials as the core of photocatalytic and photothermal processes, allowing solar energy harvesting and conversion for many technological applications, including hydrogen production, CO2 reduction, pollutants degradation, as well as organic syntheses. Particularly, photosensitive nanostructured hybrid materials synthesized coupling inorganic semiconductors with organic compounds, and polymers or carbon-based materials are attracting ever-growing research attention since their peculiar properties overcome several limitations of photocatalytic semiconductors through different approaches, including dye or charge transfer complex sensitization and heterostructures formation. The aim of this review was to describe the most promising recent advances in the field of hybrid nanostructured materials for sunlight capture and solar energy exploitation by photocatalytic processes. Beside diverse materials based on metal oxide semiconductors, emerging photoactive systems, such as metal-organic frameworks (MOFs) and hybrid perovskites, were discussed. Finally, future research opportunities and challenges associated with the design and development of highly efficient and cost-effective photosensitive nanomaterials for technological claims were outlined.
