Meso/Macroporous Inorganic Oxide Monoliths from Polymer Foams

Abstract

Low‐density bimodal inorganic oxide monoliths (see Figure) have been prepared via a two‐step procedure using macroporous polystyrene foams and amphiphilic block copolymer structure‐directing agents. The resulting meso/macroporous inorganic framework structures could be obtained with different 3D bulk shapes and for a range of inorganic oxides, as demonstrated here for silica, zirconia, and titania.
