Functional porous structures based on the pyrolysis of cured templates of block copolymer and phenolic resin

Porous materials with controlled pore size and large surface area (see Figure) have been prepared by crosslinking phenolic resin in the presence of a self-assembled block-copolymer template, followed by pyrolysis. Many phenolic hydroxyl groups remain at the matrix and pore walls, which can be used for selective and efficient absorption or further functionalization.
