Popis: Ordered mesoporous silica phases (e.g. KIT-6, SBA-15) are used as structure matrices for negative replica structures of mesoporous In 2 O 3 . We present a detailed study on how the controlled synthesis of mono-, bi- and trimodal pore systems in the products is accomplished by systematic variation of the procedure of infiltrating a precursor species (In(NO 3 ) 3 ) into the pores of the silica matrix and subsequent thermal conversion into In 2 O 3 . Melt impregnation and conversion in a closed reactor facilitates a one-step casting process for ordered mesoporous indium oxide (In 2 O 3 ). We present a model based on variation of the pore filling.
