摘要：
Two hierarchically porous silica ceramics with unidirectionally aligned channel morphology have been in situ synthesized by Using soluble starch monoliths with well-defined Uniaxial macroporous structure as template Both these ceramics faithfully Inherit the structure Of Soluble starch templates and show it large BET surface its well as,I microstructure Of Uniform worm-like nanopores and a lamellar phase. materials may be suitable for use Ill various separation and reaction processes Clown Copyright (C) 2009 Published by Elsevier Ltd. oil behalf of Acta Materialia Inc All rights reserved
