TRANSMISSION ELECTRON MICROSCOPY (TEM) STUDIES AND NITROGEN GAS ADSORPTION DATA WERE USED TO INVESTIGATE TEXTURAL CHARACTERISTICS OF TITANIAS PREPARED VIA CALCINATION, AT 400°C/3 H, OF THE HYDROLYSIS PRODUCTS OF TITANIUM(IV) ISOPROPOXIDE IN N-HEPTANE OR ISOPROPANOL SOLVENT. A VARIETY OF TITANIAS (ANATASE FORM) WERE PRODUCED WITH DIFFERENT TEXTURAL CHARACTERISTICS. THE NATURE OF THESE PRODUCTS WAS CONTROLLED LARGELY BY THE SYNTHESIS PARAMETERS ... إقراء المزيد
