Abstract

Bi-functional materials provide an opportunity for the development of high-performance devices. Up till now, bi-functional performance of NiCo₂O₄@SnS₂nanosheets is rarely investigated. In this work, NiCo₂O₄@SnS₂nanosheets were synthesized on carbon cloth by utilizing a simple hydrothermal technique. The developed electrode (NiCo₂O₄@SnS₂/CC) was investigated for the detection of L-Cysteine and supercapacitors applications. As a non-enzymatic sensor, the electrode proved to be highly sensitive for the detection of L-cysteine. The electrode exhibits a reproducible sensitivity of 4645.82μA mM^-1cm^-2in a wide linear range from 0.5 to 5 mM with a low limit of detection (0.005μM). Moreover, the electrode shows an excellent selectivity and long-time stability. The high specific surface area, enhanced kinetics, good synergy and distinct architecture of NiCo₂O₄@SnS₂nanosheets produce a large number of active sites with substantial energy storage potential. As a supercapacitor, the electrode exhibits improve capacitance of 655.7 F g^-1at a current density of 2 A g^-1as compare to NiCo₂O₄/CC (560 F g^-1). Moreover, the electrode achieves 95.3% of its preliminary capacitance after 10 000 cycles at 2 A g^-1. Our results show that NiCo₂O₄@SnS₂/CC nanosheets possess binary features could be attractive electrode material for the development of non-enzymatic biosensors as well as supercapacitors.
