摘要
以N-甲基咪唑和溴代正丁烷为起始原料,采用两步法合成了1-丁基-3-甲基咪唑四氟硼酸盐离子液体,并对所合成的离子液体做了红外光谱表征。在1-丁基-3-甲基咪唑四氟硼酸盐离子液体中,利用硼氢化钠还原氯金酸,制备了纳米金。紫外-可见光谱和透射电镜(TEM)试验结果表明,所制备的纳米金以链状为主。离子液体在纳米金制备过程中不仅起到了溶剂作用,还起到了修饰剂的作用。
1-butyl-3-methylimidazolium tetrafluoroborate ionic liquid （[BMLM]^＋[BF4]^-） was synthesized using N-methylimidazole and 1-bromobutane as starting materials by two-step method. The obtained ionic liquid was characterized by IR spectra. Gold nanochains were prepared through the reduction of HAuCI4 by NaBH4 in [BMIM]^＋[BF4]^-. UV-Vis spectra and TEM images reveal that the prepared nano gold is mainly chain-like. The ionic liquid not only acts as reaction medium but also as modifier in the preparation ofnano gold.
