Environmental Method for Synthesizing Amorphous Silica Oxide Nanoparticles from a Natural Material

Numerous studies have been performed on the generation of several silicon-based engineering materials that often used chemical high risks for health and safety environment. Generally, in synthesis Nano-silica, tetramethoxysilane, tetraethoxysilane, tetraethyl orthosilicate (TEOS) are as precursor materials; however, these toxic expensive production Nano-silica. This paper presents an environmentally friendly short method (EFSM) with efficiency amorphous silica oxide Nanoparticles by using agricultural waste called rice husks (RHs). Use EFSM alternative to methods would advantages fast simple operation, controllability, great pureness Nanoparticles, low manufacturing cost. A (NPs) evaluation was conducted energy-dispersive spectroscopy (EDS), field emission scanning electron microscope (FESEM) X-ray fluorescence (XRF). By applying method, non-toxic nanoparticles a purity 94.5% particle size less than 100 nm synthesized without any material.
