Controllable synthesis of TiO2 nanostructures with conformal and ultrathin graphitic carbon coating is critically desirable for new anode material development for Li-ion batteries. In this study, TiO2 nanoparticles (NPs) synthesized by a facile solgel method were encapsulated in graphene nanosheets (GNS) to improve the electrochemical performance. The encapsulation was facilitated by electrostatic interaction between the positively charged, silane decorated TiO2 surface and the negatively charged graphene oxi…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
