Abstract
A catalyst for the oxidation of an alkane, alkene or mixtures thereof. The catalyst includes a mixed-metal oxide having the formula MoVNbTeSbOwherein, when a=1, b=0.01 to 1.0, c=0.01 to 1.0, d=0.01 to 1.0, e=0.01 to 1.0, and f is dependent upon the oxidation state of the other elements, the catalyst further characterized by having at least two crystal phases, the first crystal phase being an orthorhombic M1 phase and the second crystal phase being a pseudo-hexagonal M2 phase, the orthorhombic M1 phase present in an amount between greater than 60 weight percent to less than 90 weight percent. The catalysts disclosed herein exhibit a chemisorption of NHof less than about 0.2 mmole per gram of metal oxide.
