The oxidative dehydrogenation of ethane comprises contacting a mixture of ethane and oxygen in an ODH reactor with an ODH catalyst under conditions that promote oxidation of ethane into ethylene. Conditions within the reactor are controlled by the operator and include, but are not limited to, parameters such as 5 temperature, pressure, and flow rate. Conditions will vary and can be optimized for a specific catalyst, or whether an inert diluent is used in the mixing of the reactants. Disclosed herein is a catalyst consisting of: Mo.sub.0-1W.sub.0.3-1V.sub.0.2-0.4Te.sub.0.06-0.10Fe.sub.0.0-0.10Nb.sub.0.08-0.18O.sub.X where X is determined by the valance of the metals.
