New strategies for 1D materials fabrication are of fundamental importance in the advancement of science and technology. Instead of the small organic amine molecule- and the polymer-directed agent, here, we report a unified graphene-oxide-directed agent for the synthesis of a series of nanoribbons with different chemistries and with low dispersity, including V2O5, AgVO3, and Sr(VO3)(2). This strategy is based on a general linear growth of vanadate and a splitting mechanism of graphene oxide during the synthesis. We believe our methodology provides a simple and convenient route to a variety of nanoribbon building blocks for assembling materials with novel structure and function in nanotechnology. More important is that graphene is in the middle of the composite structure; while supporting the main structure, it does not affect the mass transfer process. Compared to other composite structures based on graphene, such as graphene scroll and graphene sheet, graphene ribbon is more suitable for lithium-ion battery.
