“…[68] The separation step can be further upgraded by making the nanocomposite magnetic as for example GO-Fe 3 O 4 /PAA/Ag (where PAA = polyallylacid and GO = graphene oxide). [69] Incorporation of silver nanoparticles into semiconductor metal oxide such as TiO 2 can overcome the demerits associated with large band gap and hence improve the photocatalytic activity. For instance, Ag-TiO 2 nanocomposite have a band gap of 1.4 eV and exhibit visible light induced catalytic activity which otherwise (only TiO 2 nanoparticle) required UV radiation.…”

Synthetic dyes are one of the major classes of pollutant released in the environment by industries such as textile, paper, leather, rubber, cosmetics, pharmaceutical etc. They are known carcinogen and extremely hazardous to human, plant and aquatic life. Conventional chemical, physical and biological methods used for treatment of industrial effluent are costly, time-consuming and produces secondary waste. Silver nanoparticle and nanocomposite-based catalyst are very effective in decomposition of dyes due to their high surface area-tovolume ratio, stability and biocompatibility. The degradation reaction takes place in presence of light (photocatalytic) or in presence of a reagent such as NaBH 4 or H 2 O 2 .Of various methods of silver nanoparticle/nanocomposite synthesis, green synthesis has been quite popular in recent times due to ease in synthesis and sustainability factor. In this review, current state of knowledge about application of green synthesized silver nanoparticles /nanocomposites in degradation of synthetic dyes and other organic pollutant have been summarized. Moreover, the article also emphasizes on the mechanism of degradation, the kinetic parameters and optimum treatment conditions.

“…These are due to the unique physical, chemical, mechanical, optical, and electrical properties of AgNPs [3][4]. The AgNPs can be synthesized through different approaches, such as chemical reduction, sonochemical, microwaveassisted, and physical [5]. However, these approaches include several disadvantages that may have harmful effects on the environment [6].…”

Silver nanoparticles are receiving discernible attention because of their potential applications in different fields of science and technology. However, chemical synthesis methods leave behind harmful byproducts. Here, we report an alternative method for the rapid synthesis of silver nanoparticles through radiation-assisted green synthesis. Aqueous leaf extract of Ocimum sanctum is used as a reducing and stabilizing agent with silver nitrate solution under UV-B irradiation. UV-visible spectroscopy (UV-Vis), transmission electron microscopy (TEM), energy dispersive x-ray spectroscopy (EDX), photoluminescence spectroscopy (PL) and fourier transform infrared spectroscopy (FTIR) collectively revealed that bio reduced silver nanoparticles were polydisperse, polycrystalline, spherical in shape, had an average diameter of 40.1 nm, and were stable more than six months. These observations suggest that radiation-assisted green synthesis is a quick and eco-friendly method for the large-scale production of stable silver nanoparticles without any harmful byproducts.
