- Abstract (EN)
- Three-dimensional (3D) TiO₂–SnO₂–graphene aerogels (TTGs)were built up from the graphene oxide nanosheets supported with both TiO₂ and SnO₂ nanoparticles (NPs) via a facile hydrothermal assembly process. The resulting TTGs exhibit a 3D hierarchical porous architecture with uniform distribution of SnO₂ and TiO₂ NPs on the graphene surface, which not only effectively prevents the agglomeration of SnO₂ NPs, but also facilitates the fast ion/electron transport in 3D pathways. As the anode materials in lithium ion batteries (LIBs), TTGs manifest a high reversible capacity of 750 mA h g⁻¹ at 0.1 A g⁻¹ for 100 cycles. Even at a high current density of 1 A g⁻¹, a reversible capacity of 470mA h g⁻¹ can still be achieved from the TTG based LIB anode over 150 cycles.
