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.
