摘要
离子液体有不挥发、稳定性高、电化学窗口大等特点,在电化学、催化、分离等领域研究广泛。随着离子液体研究的深入和种类的不断增多.离子液体的应用范围不断扩大.在纳米材料制备方面也已经取得了一定的进展。
1-methyl-3-(ω-carboxyl)decyl imidazolium bromine ([C11OOHmim]Br) ionic liquid was synthesized and [C11OOHmim]Br modified Pd nanoparticles were prepared in solution. The morphology and structure of Pd nanoparticles were investigated by IR, TEM, XRD, XPS. The results indicated that the Pd nanoparticles were face-centered cubic structure and the diameter was between 10-30 nm. [C11OOHmim]Br was connected to the surface of Pd nanoparticles by carboxyl and Pd nanoparticles with different sizes could be obtained by varying the amount of the modifier.
