The invention discloses a preparation method of a
metal or
metal oxide particle-containing CeO2
fiber catalyst, and belongs to the field of preparation of nanocatalysts. The novel
fiber-based supported catalyst is obtained by adopting a cocatalyst CeO2
fiber as a supporter to support a main catalyst
metal or metal
oxide nanoparticle. The method comprises the following steps: 1, respectively dissolving a CeO2 precusor, a
polymer and a metal or metal salt in a
solvent, magnetically stirring, and mixing and stirring to obtain a
spinning precursor solution; 2, carrying out an electrostatic
spinning technology to make metal or metal CeO2 /
polymer supported composite precursor fibers; and 3, carrying out high temperature calcining and
hydrogen reduction to obtain the metal or metal
oxide nanoparticle / CeO2 fiber supported catalyst. The method is simple and easy, and the metal or metal oxide particle has good dispersibility and large specific surface area; and the catalyst high the characteristics of high
catalysis activity and easy
recovery, and has wide application prospect in the future
catalysis industry.
