| 摘 要： | 以十六烷基三甲基溴化铵(CTAB)为表面活性剂,NaBH4为还原剂,通过调节水相体系中CTAB和NaBH4浓度,合成了一系列不同形貌的Pd纳米粒子,合成过程简便易行且环境友好.结果表明,随着CTAB浓度的增加,Pd粒子形貌由纳米微球逐渐向纳米线网络形态转变.CTAB浓度和NaBH4浓度是决定Pd粒子形貌的两个重要因素.

| Abstract: | With cetyltrimethylammonium bromide(CTAB)as a surfactant,a series of palladium nanoparticles with various morphologies were successfully synthesized by controlling the concentrations of CTAB and NaBH4 in an aqueous solution.The morphology of the Pd NPs evolved from nanospheres as interconnected networks with a rise in the CTAB concentration.The CTAB and NaBH4 concentrations were important factors for the control of the final shape of the Pd nanoparticles. |
