Abstract Scope |
Silica monoliths, such as aerogels and xerogels, are of immense interest as a sorbent material, due to their high specific surface area, material stability and ability to be functionalized. However, traditional aerogels only offer nano- and micropores, limiting its permeability - an important factor for a monolithic adsorbent. To overcome this limitation, this work uses soybean oil as a porogen to introduce macropores within silica monoliths. Presence of nano-, micro-, and macropores creates a hierarchical pore structure that results in higher permeability as well as provision of more access to adsorption sites in the monolith. |
