| 中文摘要: |
| 以氯化钯为原料，聚乙烯吡咯烷酮(PVP)为分散剂，聚乙二醇400(PEG)为还原剂，反应温度为150℃，成功制备出纳米钯活化液。采用激光动态散射和透射电子显微镜对纳米钯进行了表征。结果显示，在PVP分散剂的作用下，得到的纳米钯为球形、单晶、粒径为30～50 nm，无其他的氧化物存在。探讨了分散剂对合成纳米钯的影响，在还原剂PEG和分散剂PVP共同作用下，制备的纳米钯粒径大小均一，无团聚现象。 |
| 英文摘要: |
| A nano-palladium activator was successfully prepared by the reaction of palladium chloride with dispersing agent PVP (polyvinylpyrrolidone) and reducing agent PEG400 (polyethylene glycol) at 150℃. DLS (dynamic laser scattering) and TEM (transmission electron microscopy) were used to characterize the nano-palladium. It showed that the obtained nano-palladium was spherical, single crystal and diameter 30~50 nm due to the dispersant effect of PVP. Palladium oxide did not exist in it. The effects of dispersants were discussed. Under the both effects of reducing agent PEG and dispersing agents PVP, the nano-palladium particles with uniform size and without agglomerated were obtained. |
