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.

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*.
