Catalytic degradation of rhodamine B by α-DMACoPc/TiO2/MIL-101 (Fe) enhanced catalytic system

Developing efficient catalysts for visible light reactions is vital in the field of photocatalysis. This study focuses on the synthesis of novel ternary composites (alpha-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.
