| 中文摘要 | in this paper, we have explored a simple and new strategy to obtain quasimonodisperse au/pt hybrid nanoparticles (nps) with urchinlike morphology and controlled size and pt shell thickness. through changing the molar ratios of au to pt, the pt shell thickness of urchinlike au/pt hybrid nps could be easily controlled; through changing the size of au nps (the size was easily controlled from similar to 3 to similar to 70 nm via simple heating of haucl4-citrate aqueous solution), the size of urchinlike au/pt hybrid nps could be facilely dominated. it should be noted that heating the solution (100 degrees c) was very necessary for obtaining three-dimensional (3d) urchinlike nanostructures while h2ptcl6 was added to gold nps aqueous solution in the presence of reductant (ascorbic acid). the electrocatalytic oxygen reduction reaction (orr, a reaction greatly pursued by scientists in view of its important application in fuel cells) and the electron-transfer reaction between hexacyanoferrate(iii) ions and thiosulfate ions of urchinlike au/pt hybrid nps were investigated. it is found that the as-prepared urchinlike au/pt hybrid nps exhibited higher catalytic activities than that of similar to pt nps with similar size. |
