Silica and alumina cryogel production
Cryogels are one of the most popular materials nowadays. They can be used in many areas due to their numerous advantageous properties. One of their most important properties is the high surface area and hierarchical pore structures. Cryogelation is an elegant way to synthetize macroporous gels: gelation is taken place under the freezing point of the solvent. As a result, gels with tailored pore structure can be produced, which can be used for heat insulators, among others.
