Tetragonal ZrO2, synthesized by the sol–gel method and dip-coating technique, was found to be photocatalytically active for degradation of methylene blue. The ZrO2 thin films were characterized X-ray diffraction (XRD), Raman spectroscopy, Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), UV-vis spectroscopy. photocatalytic blue carried out with this material. We identified tetragonal phase in film at different annealing temperatures from 400 °C 550 °C. XRD study indicated that monocrystalline nature preferred grain orientation along (011) plane exhibited a crystal structure. crystallite size increased increasing temperature. FTIR explained bonding confirmed formation composite. UV-Vis showed optical absorbance high visible region band gap value experimental results revealed degraded MB 20%, 24%, 29%, 36%, 10 h, respectively. Our provide useful insights into development materials

Semiconducting nanoparticles (SNPs) have garnered significant attention for their role in photocatalysis technology, offering a cost-effective and highly efficient method breaking down organic dyes. Of particular significance within SNP-based are tunable band gap TiO2 (NPs), which demonstrate remarkable enhancement photocatalytic efficiency. In the present work, we introduce an approach synthesis of NPs using kappa-carrageenan (κ-carrageenan), not just as reducing stabilizing agent but dopant resulting NPs. During presence sulfate-rich carrageenan, process predominantly leaves residual sulfur carbon. The carbon, conjunction with doping, indicated by fast FTIR spectra, XPS, EDX, leads to reduction composite 2.71 eV. yields degradation methylene blue (99.97%) methyl orange (97.84%). This work presents eco-friendly effective solution swift removal environmentally harmful

ABSTRACT Cost‐effective, sustainable, and eco‐friendly strategies are crucial for treating organic pollutants in industrial wastewater. ZnO is a promising photocatalyst due to its affordability, environmentally benign nature, ability fully mineralize pollutants. However, limited effectiveness under visible light major drawback. Ni doping helps reduce charge carrier recombination, enhancing the photocatalytic activity of ZnO. Ni‐Cu co‐doping increases saturation magnetization by creating intrinsic defects, though it can lead nanocluster formation on catalyst surface. Ag further improves performance preventing aggregation prolonging lifetimes. In this study, Ni‐Cu‐Ag@ZnO nanoparticles were synthesized via sol–gel method used as degradation Synozol navy blue dye. Characterization techniques like FTIR, SEM, XRD, EDX, BET, UV, PL confirmed nanocomposite structure morphology. The achieved 88% photodegradation efficiency optimal conditions (a contact time 50 min, an initial dye concentration 75 ppm, dosage 0.03 g, acidic medium with pH 2). rate constants, k 1 (2 × 10 −2 min −1 ) suggest that ordinary follows pseudo‐first‐order kinetics. Scavenging tests enhanced was driven generation OH • radicals, addition hydrogen peroxide playing key role electron–hole recombination. This indicates quantity hydroxyl radicals their adsorption determining extent degradation. study highlights potential nanocomposites wastewater treatment opens new avenues enhancement other catalysts consideration.
