Self-Assembly of Cationic Polyelectrolyte-Functionalized Graphene Nanosheets and Gold Nanoparticles: A Two-Dimensional Heterostructure for Hydrogen Peroxide Sensing
Abstract
We demonstrate the use of cationic polyelectrolyte poly(diallyldimethyl ammonium chloride) (PDDA) functionalized graphene nanosheets (GNs) as the building block in the self-assembly of GNs/Au nanoparticles (NPs) heterostructure to enhance the electrochemical catalytic ability. To ensure the GNs were modified with PDDA successfully, we study the PDDA/GNs with atomic force microscopy (AFM) and zeta potential measurements on the roughness and zeta potential changes relative to those of unmodified GNs, respectively. Then, the citrate-capped Au NPs are employed as the other model particles to construct two-dimensional GNs/NPs heterostructure. Here, the use of PDDA modifiers not only alters the electrostatic charges of graphene, but also probably provides a convenient self-assembly approach to the hybridization of graphene. Furthermore, we employ the high-loading Au NPs on graphene (GN/Au-NPs) as the electrochemical enhanced material for H(2)O(2) sensing (as the model analyte). The wide linear ranges and low detection limits are obtained using the chronoamperometry technique at the GN/Au-NPs-modified glassy carbon electrode.

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.
