Synthesis and Environmental Applications of Mesoporous Alumina

Mesoporous alumina was synthesized via the self-assembly of poly(ethylene oxide)-poly(butylene oxide)-poly(ethylene oxide) triblock copolymer and aluminum isopropoxide in the presence of nitric acid. This synthesis afforded mesoporous alumina materials with high specific surface area, large pore volume, and large pore width. This study showed that the specific surface area and porosity of alumina can be tuned to some degree by varying the polymer concentration and/or nitric acid concentration in the synthesis gel. In addition, titanium isopropoxide was added in the synthesis to prepare mesoporous titania-alumina composites that can be used in photocatalytic applications. Also, nitrogen-containing organosilica-alumina composites were synthesized in the presence of tris[3-(trimethoxysilyl)propyl] isocyanurate and examined for carbon dioxide adsorption. Finally, numerous environmental applications of mesoporous alumina were discussed.
