Nanostructured C-Pd films for hydrogen applications
We propose nanostructured carbonaceous-palladium (C-Pd) films as promising material for covering different, big surfaces as improving hydrogen storing properties material. The C-Pd films were obtained by annealing of samples prepared by physical vapor deposition on fused silica substrates. Palladium nanocrystallites placed within the film volume and also on its surface enhanced absorption of hydrogen due to dissolution of H-2 molecules in the nanocrystallites. We studied structure, morphology and topography of these films by different methods (XRD, GIXRD, SEM and EDS). XRD measurements performed in situ under H-2/N-2 atmosphere showed that alpha phase and beta phase of palladium hydride were formed. Copyright (C) 2014, Hydrogen Energy Publications, LLC.
