Sol-gel preparation of In2O3-Al2O 3 supports with controlled textural and structural properties

Alumina supports with a very narrow pore size distribution were obtained with indium-doped alumina prepared by the sol-gel method. The formation of aluminum in pentahedral coordination was identified by 27Al NMR-MAS-spectroscopy. A good correlation was obtained with the AlV NMR-MAS intensity signal and the activity in isopropanol dehydration. The insertion of In3%2b substituting some Al3%2b in the alumina network was suggested. © Springer-Verlag/Akadémiai Kiadó 2007.
