Description
Summary:A comparison of the photocatalytic activity on acetic acid (AcOH) decomposition with Pt nanoparticle (NP)-deposited, Pd NP-deposited and Pd-Au alloy NP-deposited TiO 2 will be reported in this paper. Pd and Au atoms were co-deposited on the TiO 2 surfaces via reductions of the photo-excited electrons under light irradiation. The composition, particle size, distribution and structures of the synthesized NPs were characterized by X-ray diffraction (XRD), transmission electron microscope (TEM) and X-ray photoelectron spectroscopy (XPS). The photocatalytic experiments revealed that the CO 2 elimination rate in the decomposition of AcOH was enhanced on Pd-Au-deposited TiO 2 compared to the photocatalysts of pure TiO 2 , Pt- and Pd-deposited TiO 2 .
