Adsorption and structural properties of ordered mesoporous alumina synthesized in the presence of F127 block copolymer

A facile one-pot evaporation induced self-assembly synthesis of ordered mesoporous alumina (OMA) was explored by using Pluronic® F127 nonionic triblock copolymer (structure directing agent), aluminum alkoxide (alumina precursor), nitric acid (pH adjustor) and ethanol (solvent). es of OMA samples with highly ordered cage-like structures, large spherical mesopores, high specific surface area and large pore volume were obtained and studied by nitrogen adsorption, small angle X-ray scattering, and transmission electron microscopy.
