Abstract
Niobium oxide (Nb2O5) has been prepared from a precursor solution of NbCl5 in ethanol. The effect of pH, water content for hydrolysis and calcination temperature on microstructural, spectroscopic and acidic properties has bee n studied using N-2 adsorption, X-ray diffraction (XRD), FTIR spectroscopy, temperature programmed desorption (TPD) of ammonia and DRIFTS of adsorbed ammonia. The activity for the aldol condensation of acetone was studied as well. (C) 1999 Elsevier Science B.V. All rights reserved.
