Pd-Au nanoparticles supported by TiO2 fibers were fabricated and assembled into a porous medium. The 2-16 nm Pd-Au nanoparticles were randomly dispersed in the titania nanofibers (d(a) = 117 +/- 68 nm). ray diffraction patterns and X-ray photoelectron spectroscopy verified the formation of Pd-Au particles. Binding energy shifts were detected due to chemical bonding and reduction with hydrazine monohydrate. The fiber media with Pd-Au nanoparticles had greater reactivity in conversion of NO and CO gases than Pd monometallic catalyst alone, attributed to a lower activation energy of the reaction on the Pd-Au catalyst particles.
