Dimensionally integrated nanoarchitectonics for a novel composite from 0D, 1D, and 2D nanomaterials: RGO/CNT/CeO2 ternary nanocomposites with electrochemical performance

We report a one-step conversion of a dimensionally mixed ternary nanocomposite from zero-dimensional (0D) cerium oxide (CeO2), one-dimensional (1D) carbon nanotubes (CNTs), and two-dimensional (2D) reduced graphene oxide (RGO) nanomaterials by the chemical precipitation method. The RGO/CNT/CeO2 ternary nanocomposite showed excellent electrochemical performance (electrical double layer capacitor properties) in an aqueous electrolyte followed by long term cyclic stability and high energy density compared to its binary counterparts.
