Graphene Sheets Grafted Ag@AgCl Hybrid with Enhanced Plasmonic Photocatalytic Activity under Visible Light
Abstract
Interfacing photocatalyst with graphene sheet gives rise to an extraordinary modification to the properties of the resulting hybrids. Graphene sheet grafted Ag@AgCl composite is fabricated by photoreducing AgCl/graphene oxide (GO) hybrids prepared by deposition-precipitation method. The microscopic analysis and Raman scattering reveal the direct interface between Ag nanocrystal and graphene sheet, which manipulates the electronic structures of Ag@AgCl. UV-vis absorption spectra of Ag@AgCl/reduced GO (RGO) hybrids exhibit strong absorbance in the visible region due to the surface plasmon resonance (SPR) absorption of Ag nanocrystal. In situ assembled Ag@AgCl/RGO plasmonic photocatalyst exhibits remarkable photocatalytic activity. Compared with bare Ag@AgCl nanoparticle, a 4-fold enhancement in the photodegradation rate toward rhodamine B is observed over Ag@AgCl/RGO hybrids under visible light irradiation. The large enhancement of photocatalytic activity was attributed to the effective charge transfer from plasmon-excited Ag nanocrystal to RGO, which suppress the charge recombination during photocatalytic process. This work could provide new insights into the fabrication of high performance plasmonic photocatalyst and facilitate their practical application in environmental issues.

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.
