Silica Nanoparticles from Sugarcane Bagasse Fly Ash: Converting Waste to Wealth
Abstract: The Indian cane sugar industry generates significant quantities of bagasse fly ash at boilers as a waste. This fly ash while is of no commercial value at present, also creates environmental issues. Bagasse fly ash is Si-rich and a potential resource to produce silica-based high-value products, such as silica nanoparticles (SiNPs). SiNPs have various applications, such as in crop improvement, diagnostic and therapeutic bio-analysis, membranes for fuel cells, Li-ion batteries, adsorbents, catalysts and so on. This study investigated a method to produce SiNPs from sugarcane bagasse fly ash (SBFA), which also addressed environmental issues. SiNPs have various applications. The structural properties of SiNPs were analysed using different standard techniques, viz. Scanning Electron Spectroscopy, X-Ray Diffraction Analysis and Fourier Transform Infrared Spectroscopy. This techno-economic process developed, as applied to waste material may also provide many benefits to the local agro-industry and increased attention towards silica nanoparticles will help to realize the true potential of silica nanoparticles in agriculture and in other fields.
