Three-dimensional Co₃O₄ hierarchical structures were prepared by a combination of an electrospinning method and co-precipitation reaction and characterized by scanning electron microscopy and XRD. The photocatalytic decomposition of Methylene blue (MB) on Co₃O₄ sample was investigated at room temperature. The hierarchical structured Co₃O₄ sample shows an enhanced photocatalytic performance compared with the other nanostructured Co₃O₄ powders of nanoparticles, and nanofibers, which can be attributed to the special structural feature with an open and secondary Co₃O₄ nanowire that significantly facilitates the diffusion and mass transportation of MB molecules and oxygen species in photochemical reaction of MB degradation.

Key words: Co₃O₄, heterostructures, electrospinning, co-precipitation reaction
