摘　　要：利用水热法在金属镍片表面生长出C_2NiO_4·2H_2O纳米管,经600℃退火处理得到密排六方相氧化镍纳米颗粒管。采用X射线衍射仪、扫描电子显微镜和透射电子显微镜对产物进行了物相和结构表征。通过降解亚甲基蓝试验研究了纳米颗粒管NiO的光催化活性。这种颗粒管对亚甲基蓝有较强的光催化作用,在60 min内,颗粒管状NiO对亚甲基蓝的降解率达98%,远高于Ni基的66%。The precursor C2 NiO4 · 2H2O nanotubes are grown on the surface of nickel sheets by hydrothermal method for the first time. The hexagonal NiO nano-particle tubes are obtained by annealing the precursor nanotubes at 600 ℃ for 2 h. The structure of prepared nanotubes are characterized by X-ray diffraction （XRD）, scanning electron microscopy （SEM） and transmission electron microscopy （ TEM ） respectively. degradation of methylene blue. The results Pho show tocatalytic properties of NiO tubes are studied by the degradation rate of NiO tube is about 98% in 60 rain, which is much higher than that of Ni.
