Pd-Au nano-sized alloy catalysts supported on Titania (TiO2) submicron-sized fibers were fabricated by calcination of electrospun polymer template fibers and hydrazine reduction. The morphologies, crystal structure, and textural properties (surface area, pore size, and volume) of Pd-Au/TiO2 fibers materials were evaluated with electron microscopy (SEM, TEM, and HRTEM), X-ray Diffraction (XRD), and Brunauer, Emmett and Teller (BET) nitrogen adsorption. For the alloy effect induced by the Pd-Au formation, the ensemble (geometric) effect and ligand effect (charge transfer) in Pd-Au nanoparticles were investigated with X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared spectroscopy (FTIR) to understand the formation of alloyed Pd-Au particles of different metal composition with consequent modification of their electronic and geometric properties. The catalytic activities of the materials were tested in carbon monoxide oxidation reaction using a plug-flow reactor. The results showed that the performance was optimal for a catalyst of composition Pd2Au1 molar ratio that was active at 125°C, which had higher dispersion of active components and better catalytic performance compared to monometallic particle Au/TiO2 and Pd/TiO2 fiber media. Moreover, the improved reaction activity of Pd2Au1/TiO2 fiber media was attributed to decrease in activation energy.
