构建盐水、环己烷、表面活性剂和助表面活性剂四元体系,采用可见光辅助溶致液晶模板法制备钯/聚苯胺(Pd/PANI)复合团簇,用FESEM、TEM、SAED、PXRD、FT-IR、UV-vis等技术进行了表征,并研究了Pd/PANI复合团簇对乙醇的电化学性能.结果表明,Pd/PANI复合团簇的平均粒径为412 nm,呈单分散性,Pd纳米粒子的粒径为(21±1)nm,以聚集体形式分散在PANI基体中;Pd/PANI复合团簇对乙醇展示了良好的电催化活性、抗中毒性和电化学稳定性.
Palladium (Pd)/polyaniline (PANI) composite cluster was synthesized in a quaternary system of brinecyclohexane-surfactant-cosurfactant with hexagonal lyotropic liquid crystal as template under soft visible-lightassisted condition.The samples were characterized by FESEM,TEM,SAED,PXRD,FT-IR spectroscopy and UVvisible spectroscopy.Electrochemical performance of Pd/PANI nanocomposites for ethanol oxidation was also investigated.The results show that monodisperse Pd/PANI composite cluster has the average diameter of 412 nm.Pd nanoparticles with the average diameter of (21 ± 1) nm are uniformly distributed in the PANI matrix.These Pd/ PANI composite clusters exhibit remarkable electrocatalytic activity,anti-poisoning property and electrochemical stability for ethanol oxidation.
