摘要：

Nanostructured pure Pd and Pd-Fe alloys were created by pulsed electrodeposition. increasing iron content resulted in grain size refinement. Nanostructured Pd and 7 at% Fe in Pd experienced grain growth starting at 200 degrees C. In contrast, a 20 at.% Fe in Pd alloy was stable against grain growth to above 300 degrees C, and 30 and 40 at.% Fe in Pd nanoalloys were stable against grain growth to above 400 degrees C. The Pd-Fe nanoalloys did not experience the alpha-->beta phase transition when exposed to hydrogen and had fast hydrogen absorption kinetics at room temperature with no activation being necessary.
