Ordered Mesoporous Metallic MoO2 Materials with Highly Reversible Lithium Storage Capacity

Highly ordered mesoporous crystalline MoO2 materials with bicontinuous Ia3d mesostructure were synthesized by using phosphomolybdic acid as a precursor and mesoporous silica KIT-6 as a hard template in a 10% H2 atmosphere via nanocasting strategy. The prepared mesoporous MoO2 material shows a typical metallic conductivity with a low resistivity (∼0.01Ω cm at 300 K), which makes it different from all previously reported mesoporous metal oxides materials. Primary test found that mesoporous MoO2 material exhibits a reversible electrochemical lithium storage capacity as high as 750 mA h g−1 at C/20 after 30 cycles, rendering it as a promising anode material for lithium ion batteries.
