Sol–Gel design strategy for ultradispersed TiO2 nanoparticles on graphene for high-Performance lithium ion batteries

Most recently, Prof. Dongyuan Zhao’s group reported a simple sol–gel method toward creating ultradispersed TiO2 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). Their findings revealed that the rational separation and precise manipulation of the synthesis processes of a system (involving nanoparticles nucleated, grown, anchored, and crystallized on GO sheets and the individual separation and reduction of GO sheets) together allow unprecedented control of the hybrid materials. Furthermore, they have demonstrated that the TiO2 nanocrystals/RGO sheets exhibit a high specific capacity of 94 mA h g–1 at 59 C, an excellent rate capability and cycle performance owing to the strong synergistic coupling effects. This sol–gel design strategy describes the blueprint of the rational design and controllable synthesis of useful graphene-based materials to extend their functions and achieve specific applications.
