摘要：

A study was conducted to demonstrate a forced impregnation approach to fabricate large-scale three-dimensionally ordered macroporous (3DOM) structure of metal oxides. The 3DOM structure of metal oxides was fabricated without vacancy using undiluted alkoxide precursor. The approach succeeded in impregnating reactive polymers, such as rubber, into the whole body without any ruptures of the original appearance after immerging in an acetone bath. Well-ordered 3DOM structures of TiO2, Nb2O5, Ta2O5, and ZrO2 oxides were obtained in high yield. It was observed that large fractions of the samples had highly ordered porous structure in three dimensions over a range of several micrometers. The oxides also retained the three-dimensional crystalline order of the colloidal crystal template that covered a large area and exhibited an ordered pattern of pores.
