Disclosed herein are catalyst compositions useful in selective decomposition of organic oxygenates. A feed comprising an organic oxygenate may be contacted with a catalyst comprising (a) at least 0.1 wt% of an oxide of an element selected from Group 3 of the Periodic Table of Elements, wherein Group 3 includes the Lanthanide series; (b) at least 0.1 wt% of an oxide of an element selected trom Group 6 of the Periodic Table of Elements; and (c) at least 0.1 wt.% of an oxide of at least one element selected from Group 4 of the Periodic Table of Elements, wherein the wt%s are based upon the total combined weight of the oxides in (a) through (c) and excludes any other components.
