Microstructural investigation of nanocrystalline FCC metals (Pt, Pt-Fe) embeded into a porous silicon matrix

Porous silicon with different pore sizes and / or densities impregnated with different metallic nanoparticles by various methods and techniques is subject of micro- structural investigation by X-ray diffraction, X-ray reflectivity studies and SEM imaging. Crystallite sizes, texture and phase identification is revealed and their use in various applications (biosensors, fuel cell catalyst, etc) is evaluated.
