The use of mesoporous material as a carrier is increasingly gaining significant attention in recent years. The carrier often exists in the form of organic polymers, including chitosan and starch-g-poly (L-lactide), as well as inorganic substances, namely zeolites, sulfur, and silica. In this context, silica has the greatest abundance in nature and is extensively applied as a carrier medium due to its high selectivity, excellent regeneration ability, and environmental friendliness. However, this material shows some limitations, such as high surface tension and large inter-particle bonding forces, which can be addressed through modifications of the surface area and pore size by adding surfactants. The modifications will transform silica into a mesoporous structure, suitable for use as a slow-release carrier in various applications, including catalysts, sensors, adsorbents, chromatography, drug delivery systems, and intelligent corrosion inhibitors.
