合成并表征了长链十八烷基硫醇（C18 H37 SH）钝化的钯纳米粒子。钯纳米粒子成功地被正十八烷基封端。这些钯纳米颗粒具有与体相中的I相同的面心立方晶体结构。对于各种反应条件，封端的钯纳米颗粒的尺寸在1.3-5.5 nm的范围内变化。这些结果表明，长链正十八烷基硫醇封端的钯纳米粒子比具有较短链的烷硫醇封端的钯纳米粒子更稳定。(C)2003 Elsevier Science B. V.保留所有权利。
Long-chain n-octadecayl mercaptan (C18H37SH)-passivated palladium nanoparticles are synthesized and characterized. The palladium nanoparticles are successfully capped by n-octadecayl mercaptan. These palladium nanoparticles have the same face-centered cubic crystalline structure as I'd in the bulk phase. The size of the capped palladium nanoparticles varies in the range of 1.3-5.5 nm for various reaction conditions. These results show that the long-chain n-octadecayl mercaptan-capped palladium nanoparticles are more stable than alkanethiolate-capped Pd nanoparticles with a shorter chain.
