The Journal of Physical Chemistry Letters. 3 Epub 2006 Jul 18. Our study of a (WO3)3/TiO2(110) model mixed oxide catalyst shows that this system is an extremely efficient for dehydration of alcohols, effectively lowering the energy barrier as much as possible for an endothermic reaction without yielding a significant concentration of other side products.

One way to synthesize alkenes is by dehydration of alcohols, a process in which alcohols undergo E1 or E2 mechanisms to lose water and form a double bond.  |   |  Nat Commun. 2012 Feb 21;45(2):229-38. doi: 10.1021/ar200138n.
