Reshaping carbon-coated Mn 2 Mo 3 O 8 nanotubes and enhanced sodium storage performance

Mn 2 Mo 3 O 8 /C nanotubes are successfully reshaped from micron-sized MnMoO 4 blocks using a simple microwave-combined calcination method with dopamine as both scissors and carbon source. The synthesized Mn 2 Mo 3 O 8 /C nanotube (MMOC-2) exhibits enhanced sodium storage performance as anodes for h...

Description
Summary:Mn 2 Mo 3 O 8 /C nanotubes are successfully reshaped from micron-sized MnMoO 4 blocks using a simple microwave-combined calcination method with dopamine as both scissors and carbon source. The synthesized Mn 2 Mo 3 O 8 /C nanotube (MMOC-2) exhibits enhanced sodium storage performance as anodes for half-cell (217 mA h g −1 with ca. 99% coulombic efficiency after 500 cycles) and full-cell (capacity retention of 75% after 100 cycles), which is attributed to the uniquely reshaped nanostructures with abundant active sites, short ion diffusion path and fast charge transfer.
