摘　　要：Unique self-assembled iron(II)molybdenum(IV)oxide(Fe_(2)Mo_(3)O_(8))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 Fe_(2)Mo_(3)O_(8),but also benefits the stability of the hollow structure,and thus improved the lithium storage properties of Fe2Mo3O8.The Fe_(2)Mo_(3)O_(8) 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.
