Preparation of Ordered Intermetallic PtBi co-Catalyst Nanoparticles/WO3 and its Photocatalytic Activity towards the Decomposition of Acetic Acid

The ordered intermetallic PtBi, which has a NiAs type structure (NiAs-type structure; P63/mmc, a = b = 0.431 nm; c = 0.549 nm), was prepared on the surface of tungsten oxide (WO3) using the photodeposition method and polyol method. The prepared ordered intermetallic PtBi nanoparticles (NPs) used as...

More Information
Summary:The ordered intermetallic PtBi, which has a NiAs type structure (NiAs-type structure; P63/mmc, a = b = 0.431 nm; c = 0.549 nm), was prepared on the surface of tungsten oxide (WO3) using the photodeposition method and polyol method. The prepared ordered intermetallic PtBi nanoparticles (NPs) used as co-catalyst showed much higher photocatalytic activity towards the decomposition of acetic acid (AcOH) under visible light irradiation (λ > 420 nm) than that observed with photodeposited Pt NPs/WO3.
