摘要:
以1-甲基吗啉、2-溴乙醇和四氟硼酸钠为原料,两步法合成了N-甲基-N-羟乙基吗啉四氟硼酸盐(HEMMorBF4)离子液体.产物结构由IR、1H NMR、13C NMR和元素分析确证.并以此为保护剂和还原剂制得了Au、Pd及Au-Pd合金的纳米颗粒(Au∶Pd=1∶3; Au∶Pd=1∶1; Au∶Pd=3∶1),所制的贵金属纳米颗粒平均粒径为2~3 nm.

Abstract:
The ionic liquid N-(2-Hydroxyethyl)-N-methyl-morphorinium tetrafluororate was synthesized using 1-Methyl-morpholine, 2-bromoethanol, and sodium tetrafluoroborate. The structure of the synthesized product was characterized by IR, 1H NMR, 13C NMR, and elemental analysis. Au, Pd, and bimetallic Au-Pd nanoparticles (Au∶Pd=1∶3; Au∶Pd=1∶1; Au∶Pd=3∶1) with an average diameter 2~3 nm were prepared in the ionic liquid which serves as both reductant and protective agent.
