Patent ID: 8557727

Claim:
A method of forming a catalyst, comprising: providing a plurality of support particles and a plurality of mobility-inhibiting particles, wherein each support particle in the plurality of support particles is bonded with its own catalytic particle; and bonding the plurality of mobility-inhibiting particles to the plurality of support particles, wherein each support particle is separated from every other support particle in the plurality of support particles by at least one of the mobility-inhibiting particles, wherein the mobility-inhibiting particles are configured to prevent the catalytic particles from moving from one support particle to another support particle, and wherein providing the plurality of support particles comprises: nano-sizing a precursor support powder that has an average grain size equal to or greater than 1 micron; nano-sizing a precursor catalytic powder that has an average grain size equal to or greater than 1 micron; and bonding the nano-sized catalytic powder to the nano-sized support powder, thereby forming the plurality of support particles with each support particle in the plurality of support particles bonded with its own catalytic particle.
