NiCoO@SnSnanosheets on carbon cloth as efficient bi-functional material for high performance supercapacitor and sensor applications.

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