A study of the influence of mesoporous SiO 2 on the dehydrogenation of NaAlH 4 and TiF 3 -doped NaAlH 4 revealed that the amount of hydrogen evolved is 3.8 wt% for the pristine NaAlH 4 and around 4.2 wt% for the TiF 3 -doped NaAlH 4 , but increases to 4.9-5.0 wt% once the samples are doped with meso...

Description
Summary:A study of the influence of mesoporous SiO 2 on the dehydrogenation of NaAlH 4 and TiF 3 -doped NaAlH 4 revealed that the amount of hydrogen evolved is 3.8 wt% for the pristine NaAlH 4 and around 4.2 wt% for the TiF 3 -doped NaAlH 4 , but increases to 4.9-5.0 wt% once the samples are doped with mesoporous SiO 2 in the temperature range of 100-350 °C. A favorable synergistic effect on the NaAlH 4 dehydrogenation is achieved as mesoporous SiO 2 is added as a codopant along with TiF 3 , which is associated with the nanosized pores and high specific surface area of mesoporous SiO 2 . The catalytic mechanism of mesoporous SiO 2 is more physical than chemical relative to the catalytic mechanism of TiF 3 .
