We demonstrate a fast and facile ultrasound-assisted method for the synthesis of ultrasmall SnO2 quantum dots with an average particle size of 3 nm followed by a self-assembly process on reduced graphene oxide nanosheets (RGO) to build a high-capacity anode material for lithium ion batteries (LIB). The bifunctional aminocaproic acid (AHA) plays a key role in our synthesis. It not only protected the ultrasmall SnO2 nanocrystals but also changed the SnO2 surface potential to +41.4 eV. More importantly, AHA was also used as a nitrogen source. It opens a new window to use this simple and low-cost method to fabricate complex graphene-based hybrid nanomaterials.
