摘      要：Effect of hydrolysis catalysts(HCl and C_(5)H_(8)O_(2))on structural evaluation of gelderived nanocrystalline TiO_(2) powders was *** temperature of the HCl catalyzed gel is about 200K lower than that of the C_(5)H_(8)O_(2) catalyzed *** in the later gel the anatase phase transforms to rutile at a lower temperature,and the transformation is completed in a much more narrow temperature range.
