Sol–Gel Design Strategy for Ultradispersed TiO<sub>2</sub> Nanoparticles on Graphene for High-Performance Lithium Ion Batteries LiWei WangFei FengShanshan WangJinxiu SunZhenkun LiBin LiYuhui YangJianping ElzatahryAhmed A. XiaYongyao ZhaoDongyuan 2013 The rational design and controllable synthesis of strongly coupled inorganic/graphene hybrids represents a long-standing challenge for developing advanced catalysts and energy-storage materials. Here, we report a simple sol–gel method toward creating ultradispersed TiO<sub>2</sub> nanoparticles on graphene with an unprecedented degree of control based on the precise separation and manipulation of nanoparticles nucleated, grown, anchored, and crystallized and the reduction of graphene oxide (GO). The hybrid materials show ultradispersed anatase nanoparticles (∼5 nm), ultrathin thickness (≤3 layers), and a high surface area of ∼229 m<sup>2</sup>/g and exhibit a high specific capacity of ∼94 mA h g<sup>–1</sup> at ∼59 C, which is twice as that of mechanically mixed composites (∼41 mA h g<sup>–1</sup>), demonstrating the potential of strongly synergistic coupling effects for advanced functional systems.
