“…In the study of Yan et al the hydrolysis of vaporized SiCl 4 with water vapor was carried out at the relatively low temperature of 150 °C. In addition, studies have also examined the employment of the SiCl 4 reactant in the liquid (sol–gel) synthesis method. ,, However, no studies have been published examining the possibility of industrialization of this method.…”

“…Despite significant environmental disadvantages due to its high energy consumption, the fumed silica methodology makes use of the pollutant byproduct of the polysilicon industry, SiCl 4 . 77 Thus, the utilization of this chemical as the silicon source for silica production is still highly attractive. With this in mind a number of studies 78,79 have attempted to pioneer gaseous synthesis of silica at lower temperatures achieving mixed results in terms of product size distribution and purity.…”

Colloidal silica is used in many applications including catalysis, pharmaceuticals, and coatings. Although naturally formed silica materials are widely available, they are often in forms that are difficult to process or are even harmful to health. Therefore, uniform colloidal silicas are generally manufactured using synthetic chemical processes. While established high temperature gaseous synthesis methods fall out of favor in our energy conscious society, liquid synthesis methods are current industrial leaders. The precipitated silica method provides the majority share of commercially produced specialty silicas with its economic advantages predicted to continue to grow in the future. The biomimetic method and microemulsion methods of synthesis provide a superior level of surface chemistry and morphological control than current industrial processes and are the major focus of current silica synthesis research. Movement toward more tailor-made products and ecologically friendly production methods will likely provide incentive for biomimetic methods, in particular, to take more of a market share. However, the lack of procedures to viably scale up the biomimetic and microemulsion methods still forms significant gaps in the literature. In this review, the current methods of colloidal silica synthesis are discussed alongside significant models and mechanisms of silica formation.

“…Agglomeration tendency was a problem using this method. A better way to prevent agglomeration is by adding surfactants such as octane and ethanol to the SiCl 4 system to decrease electromagnetism of the reaction system, and breaking hydrogen bond interaction [84]. The addition of ethanol in a system improved the dispersion of nanosilicon and affected the shape of the particle.…”

Agriculture waste has attracted attention as a potential source to produce raw material silicon dioxide, either crystalline (pyrophyllite) or amorphous form (geothermal sludge). It is an unwanted waste produced as a desired result of agricultural activities. Nanosilicon dioxide has undoubtedly gained eager interest in many vital industries. It is renowned for positively enhancing outstanding performance due to tuneable properties over its bulk counterpart. Silicon dioxide scientifically demonstrates a unique ability to convert efficiently into economic value from silicon-rich agriculture waste. Thus, a noble extraction from silicon-rich waste is undoubtedly gaining enormous attention. However, adequate knowledge on local optimisation of nanosilicon dioxide extraction from silicon-rich agriculture waste is lacking. Specific aims of this comprehensive review mainly highlighted a synthesis method of potential nanostructured silicon dioxide from agriculture waste and their potential applications for plant growth promoters. Reverse microemulsion, chemical vapour condensation, solid gelation, and mechanochemical are preferred methods that were typically specified to focus this comprehensive review critically. Optimisation of nanosilicon dioxide can be achieved precisely via the ideal combination of solid gelation and a high-energy ball mill process. Silicon dioxide is undoubtedly an effective agent as a plant growth promoter to overcome biotic and abiotic factors such as heavy metal uptake and translocation, inhibit pathogenic fungi, improve the antioxidant system, and mitigate various stress factors.
