Abstract
Several facile and easily controlled approaches were used to successfully synthesize Co3O4 nanomaterials including nanorods, nanosheets, nanotubes, and nanoparticles. The as-prepared samples were characterized by thermogravimetric and differential thermal analysis, x-ray diffraction, transmission electron microscopy, scanning electron microscopy, and Brunauer–Emmett–Teller (BET) surface area measurement, respectively. The photocatalytic degradation properties for methyl orange in simulated waste water using the as-prepared Co3O4 samples were investigated with assistance of hydrogen peroxide under irradiation of visible light. The results revealed that the Co3O4 with different morphologies showed different photocatalytic properties for the degradation of methyl orange. Of the samples, Co3O4 nanotubes and nanosheets exhibited higher photocatalytic activity. The repeat performances of Co3O4 nanotubes and nanosheets were measured, respectively. The results verified that the Co3O4 nanotubes and nanosheets all exhibited excellent repeatability for the catalytic degradation of methyl orange.
