摘要：

The activity and stability of bimetallic nano catalysts strongly depend on their structures, compositions, and interfaces. Here, we report the synthesis of mesoporous Pd@Ru core-shell bimetallic nanorods composed of face-centered cubic Pd and hexagonal close-packed Ru. The nanorods have two types of cavities with diameters of 3.0 +/- 0.9 and 20.3 +/- 8.1 nm. The mutual diffusion process between Ru and Pd is characterized by the high-angle annular dark field scanning transmission electron microscopy, energy dispersive X-ray spectroscopy mapping, and the synchrotron radiation photoemission spectroscopy measurements. The mesoporous Pd@Ru nanorods exhibit superior catalytic performance and stability for hydrogen evolution reactions (overpotentials of 30 mV at 10 mA.cm(-2) in 1.0 M KOH solution and 37 mV at 10 mA.cm(-2) in 0.5 M H2SO4 solution).
