The effect of heat treatment conditions on the textural and structural properties of the resulting aerogels was investigated by nitrogen adsorption-desorption, TG/DTA, XRD and TEM. The nickel-titania composite aerogel calcined and reduced under carefully controlled conditions exhibited an excellent catalytic performance for the liquid-phase hydrogenation of benzophenone to benzhydrol.
