Construction of an MoSe 2 /MoS 2 nanosheet heterostructure for enhanced sodium storage performance

An MoSe 2 /MoS 2 heterostructure composed of ultrasmall MoSe 2 nanosheets embedded in MoS 2 nanosheets was designed. Benefitting from the rich well-matched heterointerfaces between MoS 2 and MoSe 2 , it showed an excellent sodium storage performance.
