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.
