Abstract
A catalyst support structure may include a base material and a metal oxide support structure. The metal oxide support structure may be formed by loading a first concentration of precursors of a metal oxide onto the base material using incipient wetness impregnation (IWI) to form the catalyst support structure, performing a first calcination process on the catalyst support structure at a first temperature to produce first structures of the metal oxide, loading a second concentration of precursors of the metal oxide onto the catalyst support structure using IWI to at least partially cover the first structures of the metal oxide, and performing a second calcination process on the catalyst support structure at a second temperature lower than the first temperature to produce second structures of the metal oxide.
