Bamboo Derived Silicon-Carbon Particles Suitable for Renewable Energy Application

Abstract: Silicon particles was synthesized from bamboo leaf ash using a sol– gel and aluminothermic reduction techniques, while bamboo stem was carbonized through chemical activation to obtain porous carbon. The Silica gel was extracted from the bamboo leaf ash and was thereafter reduced to silicon via aluminothermic reduction by mixing the gel with aluminium powder in the ratio of 1:4. The mixture was then heated in a furnace and held at 650°C for 2 hours. After the reaction, the powder was immersed in 1M HCl solution for 6 hour to remove Al2O3 and unreacted Al powders. The synthesized materials were characterized using X-ray fluorescence (XRF) spectrometer, Fourier transform infrared (FTIR) spectrometer and scanning electron microscope (SEM). XRF analysis revealed that the bamboo leaf ash derived silica gel contained 83.67 wt% SiO2, confirming its suitability as a precursor for silicon-based anodes. SEM/EDX micrographs showed that the bamboo-derived carbon particles exhibited a porous, interconnected morphology and 73.26 wt.% carbon while the silicon particulates synthesized from the silica contains 85.24 wt.%. The findings demonstrate that bamboo is a viable, sustainable dual precursor for the synthesis of silicon–carbon particles with promising structural and compositional features for LIB anode applications. This research contributes to the development of eco-friendly, low-cost, and high capacity materials for advanced energy storage system Keywords: Sol-gel technique; Aluminothermic reduction; Bamboo leaf ash; Silica-gel; Silicon particles.
