Abstract
A catalyst includes a MgFeOx support, wherein x is a number of oxygen atoms present; ruthenium in contact with at least a portion of the MgFeOx support; and an additive including at least one of cobalt and molybdenum, where a weight ratio of the ruthenium to the additive ranges from about 1:5 to about 5:1.
