An environmently friendly solid acid catalyst, Ce(SO4)2/TiO2 was prepared simply by modifying TiO2 with Ce(SO4)2 for acid catalysis of volatile organic chemicals, 2-propanol and cumene. 7-Ce(SO4)2/TiO2 containing 7 wt% Ce(SO4)2 and calcined at 300 °C exhibited maximum catalytic activities for both reactions, 2-propanol dehydration and cumene dealkylation. The catalytic activities for both reactions were correlated with the acid amounts of catalysts measured by an ammonia chemisorption method. The asymmetric stretching frequency of the S=O bonds for Ce(SO4)2/TiO2 catalysts was related to the acidic properties and to the catalytic activity. |
