Abstract

A facile method was developed for fabricating mesoporous N-doped carbon coated Fe₃O₄ (N-mFe₃O₄@C) nanospheres using arabic gum (AG) as carbon precursor. The N-mFe₃O₄@C nanospheres can deliver a reversible capacity of 1273 mA h g⁻¹ after 200 cycles at 0.2 C and exhibit excellent rate capability of 596 mA h g⁻¹ at 1 C and 441 mA h g⁻¹at 2 C, respectively.
