Abstract Carbon doped ZnO nanoparticles have been synthesized from the thermal decomposition of Zinc citrate precursor. The precursor was semi-solid paste and then subjected to calcination at 700 °C produce nanoparticles. were characterized by Fourier Transform Infrared Spectroscopy, UV–visible (UV–Vis) spectra, Transmission Electron Microscope, Field Emission Scanning Energy Dispersive Analysis X-ray (EDAX), powder diffraction (XRD), photoelectron spectroscopy (XPS). results ensured formation hexagonal 2D-ZnO with a layer thickness 25 nm. optical band gap determined found be 2.9 eV, which is lower than bulk. Photocatalytic degradation Fluorescein dye as an anionic Rhodamine B cationic evaluated via C-ZnO NPs under UV irradiation. displayed 99% after 240 min complete photocatalytic 120

In the context of synthesizing metal doped oxide nanoparticles (NPs), green synthesis emerges as a reliable, sustainable, environmentally-friendly, and exceptional alternative to more efficient conventional chemical methods. this study, we explored co-precipitation method performed for Caesalpinia pulcherrima (C.pulcherrima) flower extract high percentage hydroxyl functional groups on terpenoid derivatives, reducing encapsulating agents, stability Ag/CuO Ag/ TiO2 NPs. The XRD patterns provided evidence highly crystalline structure monoclinic CuO, tetragonal crystal structure, face-centered cubic Ag metal, obtained improve nanosized 6 8 nm, which structural defects in materials were determined by scanning transmission electron microscopy (SEM TEM), well X-ray photoelectron spectroscopy (XPS) energy-dispersive (EDX) analyze. existence ions (Ag+), Ti4+ ions, Cu2+ CuO caused reduction carbonyl hydroxide groups, thereby facilitating formation nanostructures, demonstrated XPS Fourier transform infrared (FTIR). band gap analysis Ag/TiO2 NPs revealed that they increased catalytic activity methylene blue (MB) dye degradation efficiency achieved 86 94 %, respectively. Comparatively, with has synergistic effect leading effective antimicrobial against P. aeruginosa E. coli infections.

The co-precipitation approach was used in this study to synthesize Ag/TiO2 nanoparticles (NPs) using an extract of the flowers from C. pulcherrima. As a reducing agent and stabilizer during synthesis process, flower performed dual function. surface plasmon resonance diffuse reflectance spectroscopy spectrum provided assurance that Ag+, Ti4+ ions were significantly reduced. bandgap NPs revealed they are suitable for optical catalytic applications. analyzed X-ray diffraction (XRD) assess their size crystal structure. Through scanning transmission electron microscopy (SEM TEM), shape changes studied. Energy-dispersive (EDX) analysis employed investigate elements' chemical composition produced NPs. A Fourier transform infrared (FTIR) carried out identify functional groups might be present plant involved reduction, stabilization, bonding processes. photocatalytic disintegration hazardous organic dye pollutant methylene blue studied 40 minutes while being exposed visible light. create efficiency degradation rate 94%. Additionally, then antimicrobial capacity assessed, it discovered most effective against infections P. aeruginosa E. coli.

The Fe3O4@SiO2@ZnO composite was synthesized via the simultaneous deposition of SiO2 and ZnO onto pre-prepared Fe3O4 nanoparticles. Physicochemical methods (TEM, EDXS, XRD, SEM, FTIR, PL, zeta potential measurements, low-temperature nitrogen adsorption/desorption) revealed that magnetite surfaces, up to 18 nm in size, results formation an amorphous shell composed a mixture zinc silicon oxides. This underwent modification form Fe3O4@SiO2@ZnO*, achieved by activation with H2O2. modified retained its structural integrity, but surface groups significant changes, exhibiting pronounced catalytic activity photodegradation methyl orange under UV irradiation. It capable degrading 96% this azo dye 240 min, compared initial composite, which could remove only 11% identical conditions. Fe3O4@SiO2@ZnO* demonstrated robust stability after three cycles use photodegradation. Furthermore, exhibited decreased PL intensity, indicating enhanced efficiency electron-hole pair separation reduced recombination rate composite. process diminishes (e−)/(h+) generates potent oxidizing species, hydroxyl radicals (OH˙), on photocatalyst surface, thereby playing crucial role Fe3O4@SiO2@ZnO*.
