MoS2 Nanosheets Grown on CMK-3with Enhanced Sodium Storage Properties

摘要

MoS2 has a layered structure similar as graphite, which shows good sodium ion storage due to chemical and structural properties. In order to enhance the electrical conductivity and structural stability of the MoS2 electrode materials, we have used hydrothermal synthesis method to prepare the composite material of MoS2 nanosheets grown on CMK-3 surface. The MoS2 nanosheets have expanded interlayer spacing of the (002) plane, which is beneficial to the storage and transmission of the sodium ion with the relatively large radius. The obtained MoS2@CMK-3 nano-composite material exhibits enhanced sodium storage properties as anode materials. It delivers a reversible capacity of 323.2 mAh g~(-1) after 50 cycles at a high current density of 100 mA g~(-1), and also an outstanding rate performance.
