| 摘 要： | 金属镍在高效催化剂、传感器、导电浆料、高密度磁记录材料、高性能电极材料等领域具有广阔的应用前景,在材料科学和凝聚态物理领域引起了广泛的研究兴趣。多孔金属镍结构由金属镍骨架及孔隙所组成,与致密块体镍相比,其内部具有大量的孔隙,因而具有诸多优异的特性,如密度小、比表面积大、光学性能优异等。多孔金属镍可用来制作过滤器、催化剂及催化剂载体、多孔电极等1]。1987年Yablonovitch2]和John3]几乎同时提出了光子晶体这一新概念和新材料。构成三维模板的途径之一是在液体中自组装成具有光波量级的单分散胶体微球——胶体晶体,这…

| Abstract: | Porous metallic nickel has been synthesized using SiO2 opal as template. The template was prepared by self-assembled sedimentation of monodispersed SiO2 spheres. The metallic nickel precursor was impregnated into the void of the SiO2 opal template. The precursor transferred to metallic nickel after calcination in the nitrogen atmosphere. Then, the SiO2 opal template was removed and three-dimensional porous metallic nickel with a meso-/macroporous structure was obtained. The as-synthesized samples were characterized by XRD, FESEM and nitrogen adsorption-desorption methods. |
