Hydrothermal performance of catalyst supports (ANL-IN-09-085)

A high surface area catalyst with a mesoporous support structure and a thin conformal coating over the surface of the support structure

The high surface area catalyst support is adapted for carrying out a reaction in a reaction environment where the thin conformal coating protects the support structure within the reaction environment. In various embodiments, the support structure is a mesoporous silica catalytic support and the thin conformal coating comprises a layer of metal oxide resistant to the reaction environment which may be a hydrothermal environment.
