| 中文摘要 | the different atomic arrangements of noble metal nanocrystals with varying facets will largely affect the catalytic activity. rhombic dodecahedral, octahedral, cubic pd single-nanocrystalline crystals are exclusively enclosed by {100}, {111}, and {110} facets, respectively. herein, the electro-oxidation of hydrazine in basic solutions catalyzed by these pd single-nanocrystalline crystals was investigated. the onset potentials were about -0.48v, -0.43 v, -038 v, and -0.43 v for {110}-, {111}-, and {100}-faceted pd nanocrystals and commercial pd/c catalysts, respectively. {110} facets possess the highest specific activity and mass activity. the specific activity of pd rhombic dodecahedra was 147% higher than that of commercial pd/c catalysts. the mass activity of pd rhombic dodecahedral nanocatalysts at -0.2 v (vs. ag/agcl) was 60.3%, 113.6%, and 354% higher than that of pd octahedra, cubes, and commercial pd/c catalysts at 600 s, respectively. this study is significant to effectively utilize pd catalysts in fuel cell, industry productions, and pollutant processes.
