Structural Control of Surfactant‐Templated Mesoporous Silica Formed Inside Columnar Alumina Pores

A hybrid mesoporous membrane is developed by forming surfactant-templated mesoporous silica inside columnar alumina pores of an alumina membrane. Predominant formation of one-dimensional silica nanochannels (channel diameter = 8 nm) is achieved by controlling the aging time and temperature for preparation of the precursor solution using Pluronic P123 as a template surfactant.
