摘要：

Co3S4 porous nanosheets embedded in flexible graphene sheets have been synthesized through a simple freeze-drying and subsequent hydrazine treatment process. The robust structural stability of the as-prepared three-dimensional sandwich-like Co3S4-PNS/GS composite affords improved rate performance and cycling stability for both lithium and sodium storage.
