摘要：

A facile one-pot evaporation induced self-assembly synthesis of ordered mesoporous alumina (OMA) was explored by using Pluronic (R) F127 nonionic triblock copolymer (structure directing agent), aluminum alkoxide (alumina precursor), nitric acid (pH adjustor) and ethanol (solvent). A series 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.
