Decoration of carbon encapsulated nitrogen-rich MoxN with few-layered MoSe2 nanosheets for high-performance sodium-ion storage

The carbon encapsulated nitrogen-rich MoxN is decorated by few-layered MoSe2 nanosheets after the rational design. It is found that the MoxN as a substrate is the basis for long cycling stability, and the few-layered MoSe2 nanosheets are the key to improving the actual capacity for sodium-ion storage.
