Green Nanotechnology: Harnessing Rice Husk Ash for Nano-Silica and Characterization Insights . International Journal of Environment and Climate Change. 2023 Oct; 13(10): 3347-33542581-8627https://imsear.searo.who.int/handle/123456789/230063In the form of nanoparticles, silica is a significant inorganic component of rice husk. Consequently, it is feasible to extract high purity amorphous silica nanoparticles by straightforward thermo-chemical processes. So, in this study, an eco-friendly chemical treatment method (Green Synthesis) was used to try and manufacture amorphous silica nanoparticles from rice husk ash. I had done synthesizing silica nanoparticle in Dept. of Soil Science and Agricultural chemistry, TNAU, Coimbatore in the year 2023 and the aim of this study is to characterize the silica nano particle and use it on agricultural crops. Selected region from X-ray diffraction analysis and Transmission Electron Microscopy, silica sample exhibited amorphous behaviour as seen in the electron diffraction patterns, whereas the Fourier-transform infrared Spectroscopy spectra primarily contained siloxane and silanol groups. Images obtained in Scanning Electron Microscopy (SEM) revealed the existence of primary nanoparticles with secondary microparticles, possibly as a result of their agglomeration. These silica nanoparticles can therefore be used in the fields of microelectronics, sensors, nano-additives and will be suitable on implication on agricultural crops.Nanosilicarice husk ashamorphous silicasilanolsiloxane?(Zeta)Journal ArticleIndiaDepartment of Soil Science and Agricultural Chemistry, Tamil Nadu Agricultural University, Coimbatore – 641 003, IndiaDepartment of Soil Science and Agricultural Chemistry, Tamil Nadu Agricultural University, Coimbatore – 641 003, IndiaDepartment of Soil Science and Agricultural Chemistry, Tamil Nadu Agricultural University, Coimbatore – 641 003, IndiaDepartment of Soil Science and Agricultural Chemistry, Tamil Nadu Agricultural University, Coimbatore – 641 003, IndiaDepartment of Agricultural Microbiology, Tamil Nadu Agricultural University, Coimbatore – 641 003, India
