Abstract: Methods of preparing a sinter-resistant catalyst include forming a dual coating system. A surface of a particulate catalyst support contacts a first liquid precursor including a metal salt with an element selected from the group consisting of: aluminum (Al), cerium (Ce), zirconium (Zr), titanium (Ti), silicon (Si), magnesium (Mg), zinc (Zn), and combinations thereof. The first liquid precursor precipitates or is adsorbed as an ion on a portion of the surface forming a first coating including a porous metal oxide on the surface. The surface may be contacted with a second liquid precursor including a metal oxide sol including a metal selected from the group consisting of: aluminum (Al), cerium (Ce), zirconium (Zr), iron (Fe), titanium (Ti), silicon (Si), and combinations thereof. A second coating is formed from the second liquid precursor on a portion of the surface to create the sinter-resistant catalyst system.

Abstract: Catalysts that are resistant to high-temperature sintering and methods for preparing such catalysts that are resistant to sintering at high temperatures are provided. The catalyst may be prepared by contacting a solution comprising an ionic species with one or more charged surface regions of a catalyst support. A surface of the catalyst support further includes one or more catalyst particles disposed adjacent to the one or more charged surface regions. The ionic species has a first charge opposite to a second charge of the one or more charged surface regions. Next, the ionic species is associated with the one or more charged surface regions to form a layer on the one or more select surface regions. The layer is calcined to generate a coating comprising metal oxide on the one or more select surface regions, where the coating is formed adjacent to the one or more catalyst particles.

Abstract: Bimetallic oxidation catalyst devices include a support body, one or more metal A bulk deposits disposed on the support body, and a plurality of metal B atomic clusters disposed on the surface of each of the metal A bulk deposits. Metal A and metal B are different metals each selected from the group consisting of platinum group metals (PGM), Ag, Au, Ni, Co, and Cu, and substantially no metal B is deposited on the support body. At least 85% by weight of the metal B atomic clusters comprise up to 10 atoms and the maximum metal B atomic cluster size is 200 metal B atoms. The combined loading of metal A and metal B can be less than 1.5% by weight relative to the weight of the support body. Metal A can include Pd, Rh, Rh, or Pd, and metal B can include Pt, Pt, Ag, or Ag.

Abstract: A method of stabilizing a catalyst system includes hydrothermally treating an aluminum oxide catalyst support having ≥about 95 volume % of γ-Al2O3 phase by heating to a temperature of about 800° C. to about 1,200° C. in the presence of water. A majority of the γ-Al2O3 is converted to a stable alumina phase selected from the group consisting of: θ-Al2O3, δ-Al2O3, and combinations thereof to form a stabilized porous aluminum oxide support having an average surface area of ≥about 50 m2/g to ≤about 150 m2/g. A platinum group metal is then bound to a surface of the stable porous aluminum oxide support to form the stabilized catalyst systems.
