Three-dimensionally ordered macroporous (3DOM) nickel films are fabricated by electro-deposition into the interstitial spaces of polystyrene (PS) template formed by PS latex spheres self-assembled on nickel alloy substrates. Yttria stabilized zirconia (YSZ) precursor prepared by the sol–gel method is infiltrated in the voids of the 3DOM nickel films. After heat treatment, a novel structure of 3DOM nickel films with YSZ filled in the hollow regions (3DOM Ni/YSZ composite) has been obtained. Structure and surface morphology of the specimens were studied by X-ray diffractometry (XRD) and scanning electronic microscopy (SEM), respectively. The thermal analysis (TG-DTA) was carried out to study the thermal decomposition process of YSZ gel. When the compound specimen is calcined at 600 °C or higher temperature, the YSZ with cubic structure phase can be prepared.
