Method and system for forming plug and play oxide catalysts
An oxide catalyst is formed by vaporizing a quantity of at least one precursor material or catalyst material thereby forming a vapor cloud. The vapor cloud is quenched forming precipitate nanoparticles. The nanoparticles are impregnated onto supports. The supports are able to be used in existing heterogeneous catalysis systems. A system for forming oxide catalysts comprises means for vaporizing a quantity of at least one precursor material or at least one catalyst material, quenching the resulting vapor cloud and forming precipitate nanoparticles. The system further comprises means for supports with the nanoparticles.

a. support structures, wherein the support structure comprises a porous oxide; and
b. nanoparticles bonded to the support structures, wherein the nanoparticles comprise an oxide catalyst;
wherein the nanoparticles are attached to the support structures by an oxide-oxide bond.
2. The supported catalyst of claim 1 , wherein the oxide catalyst comprises a metal oxide.
3. The supported catalyst of claim 2 , wherein the oxide catalyst comprises lanthanum iron oxide.
