Ag@Cu2O Core-Shell Nanoparticles as Visible-Light Plasmonic Photocatalysts
Abstract
Compared to pristine Cu 2 O nanoparticles (NPs), Ag@Cu 2 O core-shell NPs exhibit photocatalytic activity over an extended wavelength range because of the presence of localized surface plasmon resonance (LSPR) in the Ag core. The photocatalysis action spectra and transient absorption measurements show that the plasmonic energy is transferred from the metal to the semiconductor via plasmon-induced resonant energy transfer (PIRET) and direct electron transfer (DET) simultaneously, generating electron–hole pairs in the semiconductor. The LSPR band of Ag@Cu 2 O core-shell NPs shows a red-shift with an increase in the Cu 2 O shell thickness, extending the light absorption of Ag@Cu 2 O heterostructures to longer wavelengths. As a result, the photocatalytic activity of the Ag@Cu 2 O core-shell NPs is varied by modulation of the shell thickness on the nanometer scale. This work has demonstrated that the Ag@Cu 2 O core-shell heterostructure is an efficient visible-light plasmonic photocatalyst, which allows for tunable light absorption over the entire visible-light region by tailoring the shell thickness.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
