The support is typically chemically inert and has a high surface area. The metal oxide typically contains a transition metal or a mixture of metals, such as rhenium, aluminum, tungsten, molybdenum, or a combination thereof. Typically, the metal oxide is mainly atomically dispersed on the surface of the support, as indicated by STEM. For example, at least 10% of the metal oxide is atomically dispersed on the surface of the support. The method includes (i) exposing a mixture of one or more alcohols or one or more esters and carbon monoxide to the catalyst. Typically, the one or more alcohols or one or more esters and carbon monoxide are in a gas phase.

Abstract: Catalyst systems are provided for reforming of hydrocarbons, along with methods for using such catalyst systems. The catalyst systems can be deposited or otherwise coated on a surface or structure, such as a monolith, to achieve improved activity and/or structural stability. The metal oxide support layer can correspond to a thermally stable metal oxide support layer, such as a metal oxide support layer that is thermally phase stable at temperatures of 800° C. to 1600° C. The catalyst systems can be beneficial for use in cyclical reaction environments, such as reverse flow reactors or other types of reactors that are operated using flows in opposing directions and different times within a reaction cycle.
