TiO 2 (not shown here). Of course at this temperature large amounts of amorphous material are still present, resulting in a high background and low diffraction intensities. The heat treatment of compound 1 at 450 °C for 2 h resulted in formation of

work of Cabral et al. [ 65 ] for the following seven oxide glasses: Li 2 O·2SiO 2 (LS 2 ); Na 2 O·2CaO·3SiO 2 (NC 2 S 3 ); 2Na 2 O·CaO·3SiO 2 (N 2 CS 3 ); BaO·2S i O 2 (BS 2 ); LiO 2 ·2SiO 2 with 0.2% mol OH (LS 2 OH); 2BaO·TiO 2 ·2SiO 2 (B 2 TS 2
) metakaolin (MK-M) for the standard and Si-rich (70.11 wt% of SiO 2 ) metakaolin (MK-T) for sand-rich. MK-M has 39.34 wt% of SiO 2 and 5.11 wt% of TiO 2 while MK-T has 28.21 wt% of Al 2 O 3 and 0.66 wt% of TiO 2 . The others elements were <3 wt% for MK

–Tropsch synthesis, including SiO 2 , Al 2 O 3 and TiO 2 etc. The porous structure of these supports could strongly affect the extent of metal reduction, morphology and catalytic properties of the active phase. Bechara et al. [ 3 , 4 ] have shown that the sizes of
Introduction Mixed or supported vanadium oxides are widely used in the partial oxidation of hydrocarbons to oxygenated products and in contaminant removal. One of the most widely investigated systems is V 2 O 5 –TiO 2 , which
