During last decade materials science developing the methods of obtaining and studying of new materials for magnetic and catalytic aplications based on nanostructured thin films and nanostructures of different metals [1,2]. Nickel due to there high magnetic and cathodic properties has technological and scientific interest. It should be noted that the magnetic and catalytic properties depend on the size of material nanoparticles, so there is an increased interest in the literature to nickel based materials having a developed surface due to the formation of metal nanoparticles with different morphology [3]. This is due to the large contribution of surface electronic states of the metal with particles size decreasing. It is also strongly affected by the structural-phase state, local atomic and electronic structure, surface morphology. Synchrotron facilities give more precise and reliable information about structure and electronic properties of materials. For instance Extended X-Ray Absorption Fine Structure (EXAFS) technique is a powerful method of obtaining of structural information and X-Ray Absorption Near Edge Structure (XANES) allows to investigate an electronic structure of materials. For the visualization of surface morphology a method of Scanning Electron Microscopy (SEM) are widely used. In this work we propose templating approaches based on the formation of Ni nanocoatings on the surface the porous alumina films with highly ordered and controlled diameter of holes. Porous alumina were obtained by anodization process of aluminum foils at different (40, 80 and 120 V) voltages. We trying to identify the influence of pores sizes on the surface morphology and local atomic structure of materials. All of the above defines the scope of work: EXAFS and SEM investigations of Ni nanocoatings to form the basis of their magnetic and catalytic properties.
