采用水热法制备形状均匀的窄分布的中孔Co3O4纳米棒,利用扫描电子显微镜、高分辨透射电镜(TEM)和选区电子衍射(ED),X 射线衍射(XRD)、X-光电子能谱(XPS)、和N2 吸附对其进行表征,研究了中孔Co3O4纳米棒的CO 催化氧化化学发光性能。结果表明,多孔纳米棒表现出较强的CO 氧化发光(CTL)强度,催化发光性质可以用于环境挥发性物质(VOCs)快速监测。 The mesoporous Co3O4 nanorods with narrow pore size distributions are prepared by a simple hydrothermal method. The samples are characterized by scanning electron microscopy (SEM), high resolution transmission electron microscopy (TEM), selected area electron diffraction (ED), X-ray diffraction (XRD), X-ray phonoelectron spectra and N2 adsorption. The chemoluminescence and catalytic oxidation properties of CO over Co3O4 nanorods are mainly investigated. The results show that the mesoporous Co3O4 nanorods show a higher catalluminescence (CTL) intensity of CO oxidation than the bulk one. Due to the high sensitivity, CTL can be used to fast monitor environmental toxic volatile organic chemicals (VOCs)
