摘要：

Urchin-like palladium nanostructures were synthesized by slow radiolytic reduction of Pd-II in cetylpyridinium chloride (CPCl) micellar solution. They were formed by polycrystalline nanowires originating from the same core. The growth process leading to these urchin-like structures has been studied. These three-dimensional (3D) nanostructures were obtained at high Pd concentration (0.1 M) which led to a relatively large quantity of nanomaterials. These nanostructures show very interesting cycling sorption properties for hydrogen storage.
