| Research Abstract |
Nanomaterials draw much attention owing to extremely high specific surface area as well as surface properties and quantum effects unlike bulk materials. Immobilized metal (oxides) nanoparticles on porous carriers were prepared by flash pyrolysis and gas-phase hydrolysis by using the carrier pores as a kind of nanoreactor. Reactant vapor was adsorbed on the carrier and then formed the product upon rapid heating or exposure to water vapor. With this facile method, titania, vanadia, rhodium (oxide), and platinum (oxide) nanostructures were successfully prepared at high yields, high loadings, and good dispersion in the carrier material.
