Opto-structural, morphological analysis of green synthesized AgNiCuO nanocomposites and their photocatalytic activity

The biogenesis of AgNiCuO nanocomposites using Bambusa seed extract as reducing and capping agents are calcinated at 500 °C. The crystal structure analysis was calculated using XRD data. The bond length of a nanocomposite was determined via FTIR analysis. FE-SEM and EDS were used to confirm the nanocomposite element composition and surface morphology. An effective core-shell-like structure of AgNiCuO nanocomposites was obtained, and the morphology of these nanocomposites was examined using a high-resolution electron microscope (HR-TEM). Selected Area Electron Diffraction (SAED) and X-ray diffraction confirmed nanocomposites are polycrystalline. The prepared green synthesis nanocomposites show the activity of the superior photocatalyst to degrade methylene Blue a hazardous dye, after 50 min of exposure to solar light radiation. The photocatalytic activity of AgNiCuO(0.050 g) at pH-7 exhibits the best photodegradation of methylene blue (MB), which also follows the pseudo-first-order kinetic model.
