Synthesis of 3D α-MnMoO4 hierarchical architectures for high-performance supercapacitor applications

Abstract

Recently, much attention has been given to the synthesis and application of 3D hierarchical nanomaterials, which can have superior performance for supercapacitors compared with other nanostructured materials. Herein, unique hierarchical nanoribbon-based 3D fan-like nanostructures of α-MnMoO₄ were controllably synthesized for the first time by using a simple method. We have assembled supercapacitors based on the hierarchical nanoribbon-based α-MnMoO₄ 3D fan-like nanostructures, which display a specific capacitance of 562 F g⁻¹ at a current density of 1 A g⁻¹, and good cycling stability with 99.8% specific capacitance retention after 1000 cycles. These results further implied that constructing unique 3D hierarchical structures can improve electrochemical properties.
