We report the transformation of mesoporous silica to its silicon replica with maintenance of structural regularity. The method employs mild displacement reactions with Mg intermetallics as the source of Mg vapor at low partial pressure. The mild conditions aid in high fidelity replication of the nanoporous framework of the starting silica.
