Silicon dioxide (SiO), also known as silica, has received attention in recent years due to wide range of capable applications including biomedical/pharmaceutical, energy, food, and personal care products. This has accelerated research in the extraction of materials from various agricultural wastes; this review investigates the extraction of silica and silicon nanoparticles from sugarcane bagasse ash with potential applications in electronic devices. Specific properties of silica have attracted the interest of researchers, which include surface area, size, biocompatibility, and high functionality. The production of silica from industrial agricultural waste exhibits sustainability and potential reduction in waste production. Bagasse is sustainable and environmentally friendly; though considered waste, it could be a helpful component for sustainable progress and further technological advancement. The chemical, biogenic and green synthesis are discussed in detail for the production of silica. In green synthesis, notable attempts have been made to replace toxic counterparts and decrease energy usage with the same quantity and quality of silica obtained. Methods of reducing silica to silicon are also discussed with the potential application-specific properties in electronic devices, and modern technological applications, such as batteries, supercapacitors, and solar cells.
二氧化硅（SiO），也称为硅石，近年来因其在生物医学/制药、能源、食品和个人护理产品等广泛应用领域而受到关注。这加速了从各种农业废弃物中提取材料的研究；本综述探讨了从甘蔗渣灰中提取二氧化硅和硅纳米颗粒及其在电子设备中的潜在应用。二氧化硅的特定性质引起了研究人员的兴趣，这些性质包括表面积、尺寸、生物相容性和高功能性。利用工业农业废弃物生产二氧化硅具有可持续性，并有可能减少废弃物的产生。甘蔗渣具有可持续性且环境友好；尽管被视为废弃物，但它可能是可持续发展和进一步技术进步的有益组成部分。详细讨论了用于生产二氧化硅的化学法、生物法和绿色合成法。在绿色合成中，人们已做出显著努力，用相同数量和质量的二氧化硅替代有毒物质并减少能源消耗。还讨论了将二氧化硅还原为硅的方法及其在电子设备中的潜在特定应用性质，以及在电池、超级电容器和太阳能电池等现代技术应用中的情况。
