Green Synthesis of Metal Nanoparticles and their Applications in Different Fields: A Review

Abstract

Nanotechnology is an art for application and handling of materials at very small scales i.e. 1–100 nm. The materials at this scale exhibit significantly different properties compared to same materials at larger scales. There are so many physical and chemical methods for the synthesis of nanoscale materials but the most appropriate are the ones that synthesize materials using green chemistry eco-friendly techniques. Recently, the collaboration between nanotechnology and biology has opened up new horizons of nanobiotechnology that integrates the use of biological materials in a number of biochemical and biophysical processes. This approach has significantly boosted up nanoparticles (NPs) production without employing harsh and toxic conditions and chemicals. This review is aimed to provide an outline of latest developments in synthesis of NPs through biotic entities and their potential applications.

Synthesis and characterization of Zn doped WO3 nanoparticles: photocatalytic, antifungal and antibacterial activities evaluation

“…In this method, colloidal solution is formed which act as precursor and coagulated into NPs [29]. The size, structure, doping efficiency and many other characteristics are characterized by SEM, XRD, FTIR, UV/Visible spectroscopy, thermal gravimetric analysis (TGA) and transmission electron microscopy (TEM) [30][31][32][33][34][35][36][37]. Nanotechnology has makes immense applications in different fields.…”

Green synthesis and characterization of carboxymethyl guar gum: Application in textile printing technology

“…Technological behaviour of CMG was studied in printing cotton fabric with reactive dyes. Major concern to textile printing is waste water pollution due to unfixed dyes and thickeners lost [33][34][35][36][37][38]. The properties of the derivatives were found comparable to native guar gum.…”

UV/H2O2, UV/H2O2/SnO2 and Fe/H2O2 based advanced oxidation processes for the degradation of disperse violet 63 in aqueous medium

“…The ·OH radicals generated attack the disperse violet 63 framework at different positions like, unsaturation points. In several such attacks the disperse violet 63 get converted into CO 2 and hetero-atoms which are further mineralized [29][30][31][32]. Results showed that degradation rate of disperse violet 63 was enhanced due to hydrogen peroxide.…”
