Abstract
The direct incorporation of Keggin-type heteropolyacid H3PW12O40 (PW) in a mesoporous organized silica molecular sieve during the synthesis was studied. The synthesis of silica-organized materials containing heteropolyacid was carried out in acidic media either by associating a non-ionic/cationic surfactants or just a non-ionic surfactant. The decomposition temperature of solids containing PW and prepared with TX100/CTMA, Tergitol 15-S-12 and Tween 60 starts at 130, 115 and 135 °C, respectively. The BET surface area of these solids is measured to be 892, 735 and 787 m2/g, respectively. Their pore diameters are equal to 31, 24 and 34 Å, respectively.
