| Abstract: | Uniform Co3O4 nanorods were prepared by a micelle-assisted hydrothermal method. The samples were characterized by scanning electron microscopy (SEM), energy disperse spectra (EDS), transmission electron microscopy (TEM), selected area electron diffraction (ED), X-ray diffraction (XRD), and N2 adsorption. The chemoluminescence and catalytic oxidation properties of CO and CH4 over Co3O4 nanorods were investigated. The results showed that the micelles played a key role in the formation of uniform nanorods, that the nanorods with a high crystallinity were obtained after being treated hydrothermally, and that the nanorods showed a higher chemoluminescence (CL) intensity of CO oxidation and a higher activity for CH4 combustion than the bulk one. The adopted ‘one-pot’ synthesis is a facile method, since no further annealing at high temperatures is needed. |
