High surface area, low density aerogels from one- and twodimensional nanomaterial

Kong, Jing (MIT, Cambridge, USA)

Aerogels have numerous applications due to their high surface area and low densities. Creating aerogels from a large variety of materials has remained an outstanding challenge. In recent years we have developed a methodology to enable aerogel production with a wide range of materials. The method is based on the assembly of anisotropic nano-objects(1D nanotubes, nanowires or 2D nanosheets) into a crosslinking network from their colloidal suspensions at the transition from semi-dilute to isotropic concentrated regime. This method is anticipated to open up wide opportunities for the applications of aerogels in catalysis, sensing and many other energy related applications.
