Low-cost and fast synthesis of nanoporous silica cryogels for thermal insulation applications
Nanoporous silica cryogels with a high specific surface area of 1095 m2 g−1 were fabricated using tert-butyl alcohol as a reaction solvent, via a cost-effective sol–gel process followed by vacuum freeze drying. The total time of cryogel production was reduced markedly to one day. The molar ratio of...
