Band Position

The Ag/AgI/Bi2WO6photocatalysts were successfully synthesized by deposition-precipitation and photoreduction methods. The catalyst showed high and stable photocatalytic activity for the degradation of the RhB under visible light irradiation (λ>400 nm). On the basis of a new plasmonic photocatalytic mechanism, the photogenerated electron-hole pairs are formed in Ag nanoparticles (NPs) due to surface plasmon resonance under visible-light irradiation. Then, the photoexcited electrons at the Ag NPs are injected into AgI. On the other hand, the band position shows that AgI and Bi2WO6have the matching band potentials in the AgI/Bi2WO6heterostructure composites. So the photoexcited electrons is ultimately transfer to the Bi2WO6conduction band (CB), photo-induced holes (hVB+) is transfer to the AgI valence band (VB) and the simultaneous transfer to compensative electrons from I-to the Ag NPS. This the result indicates that the high photosensitivity of noble metal Ag NPs due to surface plasmon resonance, which is not only improve the photocatalytic performance, but also offer a new idea for preparation of new photocatalysts .

Zeolite Catalysis

The catalytic performance of zeolites can be boosted by the electric near-field enhancement (ENFE) of plasmonic Au-NPs induced by the localised surface plasmon resonance (LSPR) under visible light irradiation.
