Abstract

A three-dimensional (3D) metal–organic framework (MOF), namely, {[Mn 4 (PBA) 4 (H 2 O) 6 ·5H 2 O]} n (Mn-PBA), has been successfully constructed from 5-(4-pyridin-3-yl-benzoylamino)-isophthalic acid ligand (H 2 PBA) and Mn(II) ions under solvothermal condition. Structural analysis reveals that there exist 1D hexagonal channels in the 3D structure along the b -axis. Mesoporous Mn 3 O 4 /C composites were fabricated by the direct thermolysis of Mn-PBA at 500 °C under an air atmosphere. When tested as a lithium-ion battery anode material, the Mn 3 O 4 /C electrode delivers an excellent capacity of 1032 mAh g –1 at 200 mA g –1 after 500 cycles along with remarkable rate capacity, which is supposed to benefit from the unique microspheres characteristic and large accessible specific area. Owing to the good cycling stability and high capacity, the Mn 3 O 4 /C electrode can be regarded as a promising anode material for LIBs.
