Claims13
A catalyst material, consisting of:
- molybdenum;
- vanadium;
- oxygen;
- and
- iron,
- wherein:
- a molar ratio of molybdenum to vanadium is from 1:0.25 to 1:0.50;
- a molar ratio of molybdenum to iron is from 1:0.25 to 1:5.5;
- and
- oxygen is present at least in an amount to satisfy the valency of any present metal oxides;
- and
- wherein the catalyst material has a Brunauer-Emmett-Teller (BET) surface area from 35 m2/g to 250 m2/g as determined by a nitrogen physisorption analysis.
