Nanostructured Silicon Derived from an Agricultural Residue Bagasse Ash via Magnesiothermic Reduction Method

This study presents the magnesiothermic reduction of silica into silicon. process occurs at a lower reaction temperature than its carbothermal counterpart. Furthermore, was extracted from sugarcane bagasse ash via thermo-chemical treatment method using, for first time, L-cysteine chloride monohydrate and used as precursor in production silicon using reduction. The as-synthesized nanocrystalline silicon’s physicochemical properties were investigated XRD, Raman, FTIR, BET, SEM. A peak 2 28.2 with crystallite size 32 nm discovered X-ray diffraction spectroscopy. pronounced around 518 cm−1 observed Raman spectrum, characteristic crystalline FTIR analysis showed two sharp peaks 446 1056 cm−1, indicative Si-O rocking mode Si-O-Si stretching functional groups present. N2 physisorption 77 K reveals that surface area, pore volume, diameter 73 m2/g, 0.23 cm3/g, 12 nm, respectively. In this study, we able to produce SCBA tube furnace, which has potential thin-film solar cells.
