A catalytic composition effective in the catalytic conversion of a feedstock alkane, such as methane, to a higher molecular weight hydrocarbon is disclosed. The composition includes a first component comprising a Group IA metal, a second component comprising a Group IIA metal, a third component, the precursor of which comprises a sol (an aqueous suspension of aluminum, silicon, titanium, zinc, zirconium, cadmium or tin) and a fourth component including a Group VIII metal, silver or a combination thereof, present in an amount effective to substantially increase the catalytic activity of the composition. In addition, methods of preparing such catalytic compositions and catalytic compositions prepared by such methods are disclosed.
