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

Abstract

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.
