The framework and/or textural porosity of mesoporous aluminas (MA), which have great potential for use in applications such as adsorbents and catalytic supports, is dependent on the conditions used in their preparation. The nanoporosity of MA affects their adsorption capacity and catalytic activity, and the bulk morphology of an MA is related to the development of the framework and/or textural porosity. An MA with a well-developed framework pore was found to have a smooth surface, while an MA with a well-developed textural pore had a coarse and aggregated morphology.
