Abstract
Developing efficient catalysts for visible light reactions is vital in the field of photocatalysis. This study focuses on the synthesis of novel ternary composites (α-DMACoPc/TiO2/MIL-101 (Fe)) by leveraging the excellent adsorption properties of MIL-101 (Fe), the photosensitizing capabilities of phthalocyanine, and the photocatalytic potential of TiO2. The nanocomposites’ structural and optical attributes were thoroughly analyzed. X-ray powder diffraction (XRD) was utilized to showcase the crystalline nature of the composites. Furthermore, Fourier transform infrared (FT-IR) studies confirmed the formation of ternary nanocomposites. Optical absorption investigations demonstrated the tuning of the optical band gap from the UV to the visible range. The results indicated that nearly 94% of the organic material was decomposed after 150 min of exposure to simulated sunlight from a xenon lamp. This high efficiency can be attributed to the synergistic interaction among the composites, enhancing light absorption. The composite’s robust stability was evidenced through cyclic tests. Valuable information was provided to advance the design and synthesis of photocatalysts consisting of metal–organic frameworks synergized with semiconductors. Exploring the possibility of mesoporous materials was based on MOFs for photodegradation of organic pollutants. The photocatalytic degradation of organic pollutants by MOFs mesoporous materials was also investigated. The potential of composite materials in the field of dye degradation of industrial waste is confirmed. The good recycling photocatalytic reusability indicates the promising application of this photocatalyst.
期刊介绍：
The objective of the Journal of Nanoparticle Research is to disseminate knowledge of the physical, chemical and biological phenomena and processes in structures that have at least one lengthscale ranging from molecular to approximately 100 nm (or submicron in some situations), and exhibit improved and novel properties that are a direct result of their small size.
Nanoparticle research is a key component of nanoscience, nanoengineering and nanotechnology.
The focus of the Journal is on the specific concepts, properties, phenomena, and processes related to particles, tubes, layers, macromolecules, clusters and other finite structures of the nanoscale size range. Synthesis, assembly, transport, reactivity, and stability of such structures are considered. Development of in-situ and ex-situ instrumentation for characterization of nanoparticles and their interfaces should be based on new principles for probing properties and phenomena not well understood at the nanometer scale. Modeling and simulation may include atom-based quantum mechanics; molecular dynamics; single-particle, multi-body and continuum based models; fractals; other methods suitable for modeling particle synthesis, assembling and interaction processes. Realization and application of systems, structures and devices with novel functions obtained via precursor nanoparticles is emphasized. Approaches may include gas-, liquid-, solid-, and vacuum-based processes, size reduction, chemical- and bio-self assembly. Contributions include utilization of nanoparticle systems for enhancing a phenomenon or process and particle assembling into hierarchical structures, as well as formulation and the administration of drugs. Synergistic approaches originating from different disciplines and technologies, and interaction between the research providers and users in this field, are encouraged.
