Mesoporous Titania Gels Prepared from Titanous Chloride and Ammonia: SEM, Nitrogen Adsorption, Thermoporometry and Mercury Porosimetry Studies

Pore-size distribution studies were carried out employing nitrogen adsorption, mercury porosimetry and thermoporometry techniques on two titania gels prepared from titanous chloride and ammonia using oxygen gas as the oxidizing agent. These gels were also characterized by scanning electron microscop...
