Method of forming a catalyst with inhibited mobility of nano-active material

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;
• dispersing the plurality of support particles in a dispersion liquid, thereby forming a dispersion of support particles;
• dispersing the plurality of mobility-inhibiting particles in a dispersion liquid, thereby forming a dispersion of mobility-inhibiting particles;
• mixing the dispersion of support particles with the dispersion of mobility-inhibiting particles, thereby forming a wet mixture;
• freeze-drying the wet mixture, thereby forming a dried mixture;
• and
• calcining the dried mixture, thereby forming a cluster of the plurality of support particles and the plurality of mobility-inhibiting 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, and wherein the mobility-inhibiting particles are configured to prevent the catalytic particles from moving from one support particle to another support particle.
