羧基功能化离子液体修饰Pd纳米微粒的制备及结构表征

Preparation and Structural Characterization of Carboxyl-functional Ionic Liquid Modified Pd Nanoparticles

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.
