Claim:
1. A method of preparing a catalyst system, the method comprising: contacting a nanoparticle bound to a support with a solution comprising a metal salt, wherein the nanoparticle is selected from the group consisting of: ruthenium (Ru) nanoparticle, rhodium (Rh) nanoparticle, palladium (Pd) nanoparticle, osmium (Os) nanoparticle, iridium (Ir) nanoparticle, platinum (Pt) nanoparticle, rhenium (Re) nanoparticle, copper (Cu) nanoparticle, silver (Ag) nanoparticle, gold (Au) nanoparticle, mercury (Hg) nanoparticle, sodium (Na) nanoparticle, potassium (K) nanoparticle, magnesium (Mg) nanoparticle, calcium (Ca) nanoparticle, barium (Ba) nanoparticle, and combinations thereof and the metal salt comprises a metal selected from the group consisting of: aluminum (Al), cerium (Ce), zirconium (Zr), titanium (Ti), silicon (Si), magnesium (Mg), zinc (Zn), sodium (Na), potassium (K), barium (Ba), calcium (Ca), and combinations thereof; precipitating the metal salts onto the particle and the support; and calcining the metal salts to generate a porous coating of metal oxide on the particle and support.
