Synthesis and characterization of ZnO, ZnO doped Ag2O nanoparticles and its photocatalytic activity

Abstract

Zinc oxide (ZnO) has a variety of characteristics, including optical, electrical, mechanical, thermal, and structural. Nanoparticles (NPs)play a big part in many different industries. The current research focuses on producing ZnO Nps for photocatalytic dye degradation activities. Ag2O-doped ZnO was produced together with three other different types of ZnO NPs. Nps as well as pure ZnO nanocrystals, were recovered using chemical and biological methods. The SEM study supported the chemical evolution of the ZnO nanorod-like structure, which exhibits enhanced photocatalytic activity. It was predicted that chemically produced ZnO Nps would have 34 nm, the typical particle size. X-ray diffraction analysis was used to identify Ag2O/ZnO nanoparticles in their hexagonal configuration. The particle size ranged from 16 to 17 nm, which was shown to be the norm. The findings of the SEM study further demonstrate that the created Ag2O doped ZnO Nps agglomerated into hexagonal forms, stuck together as bulks and rods, and grew in size in proportion to the Ag nanofluids. We conclude that hexagonal and rod-shaped Ag2O/ZnO Nps aggregates work well as photocatalytic catalysts. Approximately 25 mL of ZnO-doped Ag2O nanofluid is a powerful photocatalyst for oxidizing organic dyes and is suitable for large-scale applications
