Silica or various silicate aerogels can be characterized by highly porous, open cell, low density structures. The synthesis parameters influence the three-dimensional porous structures by modifying the kinetics and mechanism of hydrolysis and condensation processes. Numerous investigations have shown that the structure of porous materials can be tailored by variations in synthesis conditions (e.g., the type of precursors, catalyst, and surfactants; the ratio of water/precursor; the concentrations; the medium pH; and the solvent). The objectives of this review are to summarize and elucidate the effects of chemical conditions on the nanoporous structure of sol-gel derived silicate aerogels.

• A multifunctional hierarchical porous SiO2/GO membrane for high efficiency oil/water separation and dye removal (2020, background): “For the SiO2/GO membranes, the characteristic bands of GO (such as C=O, C-O, C-O-C, and C-N) are reserved, and a new strong peak at 1076 cm emerged that can be attributed to Si-O-Si stretching vibrations of the SiO2 particles [43].”
