Metal organic frameworks (MOFs) are widely used in the synthesis of metal oxides as important organic–inorganic compound precursors. A perovskite ABO3-type Co-based MOF [NH4][Co(HCOO)3] was synthesized from a simple mixture without any adjuvant. Porous Co3O4 microspheres are used as anode materials for lithium-ion batteries (LIBs), which are obtained from [NH4][Co(HCOO)3] as a precursor through a pyrolysis process in air. The obtained pagoda cauliflower-shaped Co3O4 microspheres exhibit an excellent electrochemical performance.
A MOF is employed as a template and carbon resource for the synthesis of porous carbon-coated CuCo2O4 concave polyhedra, exhibiting an excellent capacity and cycling reversibility.
Ultrasmall Co3O4 nanoparticle with thin porous carbon shell is reported by employing metal–organic framework as precursor and CO2 as oxidizing atmosphere, which exhibits a long cycling stability and high rate performance for Li-ion battery.
TiNb2O7 anode constructed with carbon-coated nanosheet arrays on carbon cloth is prepared by a facile solvothermal process and post carbon-coating for the first time. With nanosized diffusion-length and reduced polarization...
