Facile electrochemical synthesis of CeO2 hierarchical nanorods and nanowires with excellent photocatalytic activities

Abstract

In this work, we developed a simple, cost-effective and controllable electrochemical method to synthesize free-standing CeO₂ hierarchical nanorods and nanowires. Due to their hierarchical one-dimensional nanostructures and increased surface areas, both the CeO₂ hierarchical nanorods and nanowires exhibit substantially higher photocatalytic performance than the commercial CeO₂ nanoparticles in the degradation of methyl orange.
