中文摘要	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 h2o2 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.
