Heterostructure Enhanced Sodium Storage Performance for SnS2 in Hierarchical SnS2/Co3S4 Nanosheet Array Composite

Herein, a uniformly distributed SnS2/Co3S4 heterostructure nanosheet array was grown on carbon cloth (CC) fibers by a solvothermal method and an oil bath method. The protective layer of Co3S4 nanoparticles can enhance the sodium storage performance.
