Title
Visible light induced decomposition of organic compounds on WO3 loaded PtPb co-catalysts
Abstract

•The WO3 supported PtPb catalysts was synthesized.•The formation of PtPb catalysts were characterized with TEM and XPS.•The photocatalytic activities of the PtPb/WO3 were investigated.

Tungsten oxide (WO3)-supported ordered intermetallic PtPb nanoparticles (PtPb NPs/WO3) were prepared through a co-reduction of Pt and Pb precursors with sodium borohydride in anhydrous methanol containing WO3. The PtPb NPs/WO3 were characterized based on the crystal structure obtained through powder X-ray diffraction (pXRD) as well as X-ray photoemission spectroscopy (XPS) and transmission electron microscopy (TEM). The formation of an ordered PtPb intermetallic phase on the WO3 surface was confirmed. The PtPb NPs/WO3 were more efficient when decomposing acetic acid (AcOH) and acetaldehyde (AcH) with visible light irradiation compared to the same process over WO3 loaded with Pt nanoparticles (Pt NPs/WO3).
