Rapid Sonochemically Assisted and Environmentally Benign Green Synthesis of Silver Iodide Nanoparticles with Photocatalytic Properties

摘要

The aim of the present work was to explore the effect of D-glucose as reducing agent as well as capping agent in the ultrasound wave mediated sonochemical synthesis of AgI nanoparticles. In the present research work, spherical shaped AgI nanoparticles (NPs) are produced by using a mixtureof silver nitrates, potassium iodide as precursors and D-glucose as reducing agent. The eco-friendly synthesized silver iodide NPs were characterized by powder X-ray diffraction (PXRD), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), Fourier transform infraredspectroscopy (FTIR), UV-Vis spectroscopy and photoluminescence (PL) spectroscopy. The PXRD result indicates crystalline nature of AgI NPs with the particle size of 27 ± 3 nm respectively. In addition, the photocatalytic degradation of the AgI NPs was evaluated by the decomposition oforganic dyes with a concentration of 10 ppm under visible light irradiation. The highlights of utilizing D-glucose in sonochemical synthesis of AgI NPs is less reaction time, economic, eco-friendly, one step method and is devoid of organic solvents which are toxic to living organisms as wellas the environment.
