Preparation of Hierarchical MnCo ₂ S ₄ Nanotubes for High‐Performance Supercapacitors and Non‐Enzymatic Glucose Sensors

Abstract

Abstract Hierarchical MnCo 2 S 4 nanotubes have been successfully prepared via a facile self‐template approach. The as‐prepared hierarchical MnCo 2 S 4 nanotubes are evaluated as electrode materials for supercapacitors, which exhibits a specific capacitance of 705.2 F g −1 at 0.5 A g −1 and a remarkable cycling performance. Moreover, the hierarchical MnCo 2 S 4 nanotubes are also applied in non‐enzymatic glucose sensors, which possesses good electrocatalytic performances with a low determination limit (0.1 μM) and good selectivity. In addition, yolk‐shelled MnCo 2 O 4 prisms were also prepared via the self‐template method. The electrochemical performance of the yolk‐shelled MnCo 2 O 4 prisms were also studied. It is found that the as‐prepared hierarchical MnCo 2 S 4 nanotubes show better electrochemical performances than yolk‐shelled MnCo 2 O 4 in this work.
