The unique properties of the Sn-S system made it a high sensitiveness nanomaterial for prepare higher-performance supercapacitors. The heterostructured SnS₂/SnS and N-CNOs were synthesized by simple solvothermal and pyrolysis methods, respectively. To improve the conductivity of the SnS₂/SnS composite, N-CNOs were added to the pristine SnS₂/SnS. Herein, an ultrasensitive supercapacitor based on SnS₂/SnS and N-CNOs was fabricated. Compared to the pristine SnS₂/SnS heterostructured composite, SnS₂/SnS/N-CNO showed high supercapacitance performance due to the increase in conductivity with the addition of C-based N-CNOs. Regarding that SnS₂/SnS/N-CNO has superior electrochemical performances comparable to SnS₂/SnS, because of the fast electronic transportations and volume changes in the formations of SnS₂/SnS/N-CNO heterostructures. The electrochemical performance of the SnS₂/SnS/N-CNO electrode enhanced specific capacitance value of 741.67 F g⁻¹ from SnS₂/SnS electrode specific capacitance of 350 F g⁻¹ at a 0.5 A g⁻¹ and it showed excellent cycling stabilities of 95% retention even after 2000 cycles. The obtained results suggest that the SnS₂/SnS/N-CNO is efficient to be applicable as a novel electro-active source in supercapacitor devices to render higher performances and stable energy storage applications.
