Abstract
A textured catalyst having a hydrothermally-stable support, a metal oxide and a catalyst component is described. Methods of conducting aqueous phase reactions that are catalyzed by a textured catalyst are also described. The invention also provides methods of making textured catalysts and methods of making chemical products using a textured catalyst.
Claims11
A method of catalyzing a reaction comprising:
- passing an aqueous mixture comprising at least one reactant into a reaction chamber;
- providing a catalyst within the reaction chamber, the catalyst comprising
- a hydrothermally stable support having an exterior surface;
- a metal oxide;
- and a catalytic metal, at least 5% of the catalytic metal being disposed within pores that are at least about 10 μm away from the exterior surface of the support;
- reducing the at least one reactant in the presence of the catalyst and under hydrothermal conditions, the reducing occurring at a pH of from about 1 to about 6;
- and
- obtaining at least one reduction product from the reaction chamber, wherein the reduction product obtained has a higher purity or a higher yield than where the reaction is conducted at a pH that is 4 or more pH units from the pH of said aqueous solution.
