Organised mesoporous and microporous aluminas have been synthesised by a sol-gel route in non-aqueous media using polyethylene oxide surfactants as directing agents. The use of 1,4-dioxane as solvent enables the control of pore size in mesoporous aluminas. Aluminum coordination is modified by addition of ammonium fluoride, ethyl acetoacetate or triethanolamine to the synthesis gel. The chelating ligands modify the alumina porous structure and generate microporosity.<
