通过用甲醇或2-丙醇还原氯化钯（II）形成的钯纳米颗粒通过截留在固体重氟化化合物中而稳定，如粉末X-射线衍射所示。一些稳定剂是没有官能团的氟代烃。计算表明，少量的Pd（II）的纳米粒子的表面上可能是有吸引力的相互作用与全氟链（CnF 2n +1）的负周边的起源。乙酸钠在纳米颗粒沉淀中的作用被强调。
Palladium nanoparticles formed by the reduction of palladium(II) chloride with methanol or 2-propanol are stabilized by entrapment in solid heavily fluorinated compounds, as suggested by powder X-ray diffraction. Some of the stabilizers are fluorohydrocarbons without a functional group. Calculations suggest that minor amounts of Pd(II) on the surface of the nanoparticles might be the origin of attractive interactions with the negative periphery of perfluorinated chains (CnF2n+1). The role of sodium acetate in the precipitation of nanoparticles is underlined.
