Graphene–metal–oxide composites for the degradation of dyes under visible light irradiation
Abstract
Reduced graphene oxide (RGO) was respectively modified with tin dioxide (SnO2) and titanium dioxide (TiO2) via a direct redox reaction between the graphene oxide (GO) and the reactive cations Sn2+ and Ti3+, forming RGO–SnO2 and RGO–TiO2 composites. During this redox reaction, GO was reduced to RGO while Sn2+ and Ti3+ were oxidized to SnO2 and TiO2, depositing on the surface of the RGO. The composite materials were found to exhibit very interesting photocatalytic properties for degrading Rhodamine B under visible light irradiation. First, their photocatalytic activities were higher than that of P25 (a commercial TiO2 as a benchmark photocatalyst). Second, the reaction mechanism catalyzed by the composite materials was different from that of semiconductor photocatalysis. Characterization data showed that the excellent photocatalytic performance of the composite materials was associated with the good electrical conductivity and effective charge separation because of the presence of RGO. The present work opens up a new avenue to preparing RGO-based composite materials and provides new insights into the photocatalytic degradation of dyes under visible light irradiation.

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.
