This study presents the preparation and comprehensive characterization of nanoparticles and a nanocomposite synthesized through the mediation of green tea extract. Zinc oxide (ZnO) and titanium dioxide (TiO2) nanoparticles, as well as a TiO2-ZnO nanocomposite, were synthesized using green tea extract as a reducing and stabilizing agent. Characterization techniques including Scanning Electron Microscopy (SEM), Elemental Dispersive X Ray analysis (EDX), Fourier Infra-Red Spectroscopy (FT-IR) were employed to confirm the shape, elemental and chemical composition of the synthesized materials. The synthesized ZnO nanoparticles exhibited uniform spherical morphology, while the TiO2 nanoparticles displayed a fine, rounded rhombic shape. The TiO2-ZnO nanocomposite exhibited a combination of rhomboid and spherical particles, demonstrating its complex and heterogeneous structure. The study highlights the potential of green tea-mediated synthesis for producing nanoparticles and nanocomposites with diverse morphological features, offering opportunities for various applications in nanotechnology and materials science.
