Abstract
Disclosed are heterostructured silica catalysts (modified Haider heterostructured silica) and methods of their use and preparation. The heterostructured silica catalysts include a transition metal, an alkaline earth metal oxide, and silica, wherein the transition metal, the alkaline earth metal from the metal oxide thereof, and silicon (Si) from silica are each present in the crystal lattice structure of the catalyst. The catalyst can have application in, e.g., the hydrogenation of carbon monoxide.
