英文摘要 | Monodisperse hollow mesoporous PdCo alloy nanospheres are prepared via a simple galvanic replacement reaction. The as-prepared PdCo hollownanospheres have small diameter, such as Pd78Co22 nano spheres of diameter about 25 nm and mesoporous shells about 4-5 nm. The Pd78Co22 hollowmesoporous nanospheres possess the largest electrochemical active surface areas (ECSA, 53.91 m(2) g(-1)), mass activity (1488 mA mg(-1)) and specific activity (2.76 mA cm(-2)) towards to methanol oxidation relative to the Pd68Co32, Pd92Co8 hollow mesoporous nanospheres and commercial Pd/C catalysts. Moreover, the activity of Pd78Co22 after long-term stability tests is still the best and even better than those of fresh Pc188Co32 and commercial Pd/C catalysts. The PdCo catalysts not only effectively reduce the Pd usage by forming hollow structure, but also fully realize the Pd-Co alloying effects forenhancing the methanol oxidation catalytic performance. |
