摘要

Recent research in the field of nanotechnology revealed that plant extract and their derivatives are good stabilizing and reducing agents. Artemisia stelleriana (Dusty Miller) is widely used as an ornamental plant. The current study, explores one-pot method to synthesise A. stelleriana-mediated silver/ zinc oxide nanocomposites (AS-Ag/ZnONCs). Using UV-visible spectrophotometer, scanning electron microscopy, energy-dispersive X-ray, Transmission Electron Microscope, X-ray diffraction, and Fourier transform infrared spectroscopy the characterisation of the synthesised AS-Ag/ZnONCs was examined. The crystalline size of the AS-Ag/ZnONCs was determined to be 45.39 nm using the Williamson-hall equation. Irregular-shaped nanocomposites were observed from AS-Ag/ZnONCs, exhibiting an average size of 35.2 nm. To check the activity of AS-Ag/ZnONCs as photocatalysts to degrade RY145, RY86, RB222A and RB220 dyes was determined. The order of photocatalytic activity of AS-Ag/ZnONCs was as follows: RY145 > RB220 > RB222A > RY86. Low toxicity was observed when Vigna radiata (Mung bean) and Artemia salina (Brine shrimp) were exposed to treated dye solutions using AS- Ag/ZnONCs when compared with untreated dye solutions.
