摘要

Abstract

Mesoporous titanium containing alumino-silicate materials with various titanium/silicon (Ti/Si) ratio (AlSi-Ti(

);

= Ti/Si mole ratio) have been successfully synthesized by a novel single-step sodium (Na)-free method

for the first time. The obtained characterization results of the prepared materials reveal that

in-situ

addition of Ti into AlSi shows ordered mesoporous structure along with uniformly dispersed Ti species in +4 and +3 oxidation states suitable for selective oxidation of allylic C—H bond. The prepared mesoporouse Ti-AlSi(

) samples exhibited excellent activity in the oxidation of cyclohexene with 100% conversion and 100% selectivity to ketone-alcohol (KA) oil (cyclohex-2-en-1-ol and 2-cyclohexen-1-one) at low temperature and reaction time (35 ℃ and 30 min reaction time). This study suggests that AlSi-Ti(0.05) material can be a promising catalyst for the selective oxidation of cyclohexene under mild reaction conditions.
