摘要: A one-step approach to synthesize functional two-dimensional graphene/SnO2 composite nanosheets (GSCN) is reported. It should be noted that SnCl2 not only a reducing agent for graphene oxide (GO), but also precursor of SnO2. On the other hand, polyelectrolyte poly(diallyldimethylammonium chloride) (PDDA) was introduced simultaneously in preparation, endow it with an ideal self-assembly building block. Through electrostatic interaction, general method has been developed preparation ternary GSCN/nanoparticles (GSCN/NPs) hybrid structures high-density noble metal NPs. Prominent examples including Au, Pt and Au@Pt NPs could loaded on surface GSCN. Furthermore, we employed supported GSCN as electrochemical material nonenzymatic glucose detection, which exhibited good electrocatalytic activity.
