Unique self-assembled iron(II) molybdenum (IV) oxide (Fe₂Mo₃O₈) mesoporous hollow spheres have been facilely constructed via the bubble-template-assisted hydrothermal synthesis method combined with simple calcination. The compact assembly of small nanoparticles on the surface of the hollow spheres not only provides more active sites for the Fe₂Mo₃O₈, but also benefits the stability of the hollow structure, and thus improved the lithium storage properties of Fe₂Mo₃O₈. The Fe₂Mo₃O₈ mesoporous hollow spheres exhibit high initial discharge and charge capacities of 1189 and 997 mA·h·g⁻¹ respectively, as well as good long-term cycling stability (866 mA · h · g⁻¹ over 70 cycles) when used as a lithium-ion battery anode. This feasible material synthesis strategy will inspire the variation of structural design in other ternary metal molybdates.

通过气泡模板辅助水热合成与简单煅烧相结合，轻松地构建了独特的自组装氧化铁（II）钼（IV）（Fe ₂ Mo ₃ O ₈）介孔空心球。小纳米颗粒在空心球表面上的紧密组装不仅为Fe ₂ Mo ₃ O ₈提供了更多的活性位点，而且有利于空心结构的稳定性，从而改善了Fe ₂ Mo ₃的锂存储性能O ₈。Fe ₂ Mo ₃ O ₈当用作锂时，介孔空心球分别显示出高的初始放电和充电容量1189和997 mA·h·g ^-1，以及良好的长期循环稳定性（在70个循环中为866 mA·h·g ^-1）离子电池阳极。这种可行的材料合成策略将启发其他三元金属钼酸盐的结构设计变化。
