Extraction and synthesis of silicon nanoparticles (sinps) from sugarcane bagasse ash: A mini-review. Applied Sciences (Switzerland). 12(5), 2310. https://doi.org/10.3390/app120523102076-3417https://doi.org/10.3390/app12052310http://hdl.handle.net/10566/8021This current study reviews the utilization of the traditional extraction methods and latest findings in extraction of silica from agricultural wastes, in particular, sugarcane bagasse, using inorganic acids to produce nano-silicon. The three key processes discussed in detail include elec-trochemical, ball milling, and sol–gel processes. The sugarcane bagasse has been identified as the cheapest source of producing silica from the potential raw material for the preparation of nano-silicon. The acid-base extraction and precipitation methodology involves the use of bases like sodium hydrox-ide (NaOH) and potassium hydroxide (KOH), and acids such as hydrofluoric acid (HF), sulphuric acid (H2SO4 ), nitric acid (HNO3 ), and hydrochloric acid (HCl) for the treatment of the ash.enSugarcaneGreen technologyChemistrySilicaSiliconArticle
