Structural insights into zinc oxide-silver nanocomposite <i>via</i> different XRD models: rapid synthesis with photocatalytic & antibacterial applications.

ABSTRACT: In this work, a silver-coated zinc oxide nanocomposite (ZnO/Ag NC) was synthesized via a sol-gel method combined with ultrasonic irradiation. SEM analysis revealed uniform particle size and morphology, while UV-vis spectroscopy showed a slight absorption shift due to silver incorporation, and FT-IR confirmed successful Ag coating on ZnO nanoparticles, which was further applied to degrade methylene blue dye and showed stronger antibacterial activity against both Gram-positive and Gram-negative bacteria compared to pure ZnO. Detailed XRD studies confirmed a well-defined wurtzite structure and revealed that the material is semi-crystalline with crystallite sizes ranging from 1 to 100 nm, averaging about 74 nm. Crystallographic parameters such as crystallite size, internal strain, and c
