“…The maximum documented silica gel production for other feedstocks, including palm shell, was lower than the present precursor with the best silica gel yield 92% [54], corn cob 47% [19], bamboo Leaf 79.38% [49], sugarcane leaf 80.50% [55], wheat straw (7.00% [21], and rice straw 76.70% [56]. The highest yield from the TS was, however, only slightly higher than that of sugarcane bagasse and rice husk, both of which have yields greater than 95% [57] and 96% [13,46], respectively. This demonstrates that one of the potential precursors for producing silica gel can be the TS.…”

“…Therefore, it is an essential to look for a feasible and affordable method to produce silica gel. In this line, as a substitute in this case, preparation of silica gel using leftover biomass, such as rice husk ash [13], sugarcane leaf [14], palm tree [15], rice straw [16], oat husk [17], sugarcane bagasse [14], coffee husk [18], corn cob [19,20], wheat straw [21], maize leaves [22], bamboo leaf [23], and teff straw [24] are gaining more interest because of this approach addresses simple manufacturing procedure and economically affordable , can be a better option.…”

“…From the ash of agricultural wastes, silica gel can be extracted using the sol-gel technique through acid treatment to transform into gel [34]. Studies revealed that the sol-gel method can yield the highest silica gel, up to 96%, from rice husk ash [13]. In studies elsewhere, it has been proven that the TSA can yield approximately more than 91% silica gel via the sol-gel method [35,36] and followed by rice straw (90.56%) [21] and 84.60% [37].…”

Bio-based silica gel is having many commercial significances in various sectors, such as medical, cleansing agents in industries, laboratory analysis, cosmetics, food additives, and so forth. In view of crucial requirements, this study aimed to synthesize and characterize the silica gel from Ethiopia’s primary post-harvest biomass residue, known as teff straw. The present study has been emphasized to investigate on the influence of calcination time for teff straw ash [Joshi et al 2022 Investigation of bamboo leaves as an alternative source of silica: extraction, characterization and its application as an adsorbent for methylene blue sequestration Chem. Select. 7, e202200011] preparation between 2 to 5 h. Further, the specific surface area of the resultant TSA samples was examined for preliminary understandings of processing time. By adopting the standard procedures through template-mediated sol–gel process, acquired TSA samples were subjected to treatment with NaOH to result sodium silicate solution and the amorphous silica. From the findings, it was apparent that the yield of silica gel has significantly influenced by calcination time. Accordingly, the maximum yield (90.0%) was attained at the calcination time of 4 h at 900 °C. Further, physiochemical and morphological characteristics of acquired silica gels were ascertained using sophisticated instrumental techniques such as BET, FTIR, XRD, SEM, and EDX. The XRD analysis of the crystallographic characteristics showed that the silica extracted from TSA at 900 °C for 2, 3, 4, and 5 h was found to be in amorphous state. The surface morphological studies of silica gel samples have been carried out using SEM studied. the EDX spectra showed the negligible amount of other impurities, nevertheless a larger amount of silica was found with highest purity of 99.77% e silica gel was obtained in TSA calcinated at 3 h. FTIR spectrum confirmed the presence of siloxane (Si–O–Si) vibrations of amorphous silica that are responsible for the strong bend observed at 1070 cm−1. It was found that the silica gel prepared at 3 h of calcination time had the largest specific surface area of 739.242 m2 g−1, pore volume of 0.32 cm3 g−1, and a pore diameter of 1.68 nm.

“…Te bandgap energy is the primary factor that determines how a semiconductor interacts with other materials. Te difference between the valence band and the conduction band section, which defnes the amount of transition energy required to convert the electron band from the valence band to the conduction band, is determined by the energy bandgap [182]. Bandgap energy for semiconductors ranges from 0 to 4 eV, whereas it is beyond 4 eV for isolators and below 0.5 eV for conductors [183].…”

Silica has shown numerous applications in different fields such as environmental, biomedical, agriculture, and even in chemical processing. However, due to high energy-intensive and cost-effective issues, researchers show interest to replace the conventional methods with biobased environmentally-friendly techniques for biosilica production from renewable biomass sources. Generally, silica is found to be available in amorphous and crystalline structures. For commercial purposes, silica is produced from alkyl orthosilicates ore that consists of polyethlydiorthosilicate, tetraethyl ortothosilicate, and tetramethyl orthosilicate. Another form of silica, silica gel, is produced from the selected resources of biomass, such as palm tree, wheat straw, maize leaves, teff straw, sugarcane bagasse, rice husk, rice straw, sugarcane leaf, oat husk, bamboo leaf, and corn cob. The production of biobased silica gel from agricultural residues is found to be a sustainable which receives a significant attention that can be replaced with inorganic-based silica gel for environmental concerns. Based on this context, there is a huge look for developing a process to produce biobased silica and silica gel from biomass resources with low energy utilization as promising alternatives to conventional methods. Keeping in view, current trends and methods for synthesis, the characterization of biobased silica and silica gel, as well as its wide prognostic applications were focused on a comprehensive review.

In this article, the chemical and mineralogical composition of the local quartz sands of Surkhandarya region was initially determined by the method of X-ray phase analysis. The sand was then washed and dried several times in distilled water for enrichment. The resulting clean sand was crushed, sifted and returned with magnesium at temperatures of 600–1800°C at intervals of 2–10 hours, technical Silicon (93%-94%) was obtained. Silicon oxide and magnesium metal for magniothermal extraction 2:1, 1:1, 1:2, 1:3, 1:4, 1:7 the goods were taken in proportions. It was washed three to four times in distilled water, hydrochloric acid, alkali to extract Silicon from the composition of the resulting reaction mixtures. The purity of the extracted Silicon was studied using X-ray phase and element Analysis. The study found that the optimum temperature for reaction of silicon oxide with magnesium was 800°C temperature, reaction duration was 6 hours, with a molar ratio of silicon oxide and magnesium of 1:2, the reaction yield showed the highest result of 98,8%.
