Synthesis and Characterization of multi-walled carbon nanotube/gold nanoparticle heterojunctions
首发时间:2009-01-20
Abstract:Multi-walled carbon nanotube/gold nanoparticle (MWCNT/Au) heterojunctions were synthesized in high yield by a sulfhydryl-functionalized self-assembly strategy. Component, size, structure, morphology, and bond mode of the MWCNT/Au heterojunctions prepared thus were investigated and demonstrated by TEM, SEM, XRD, EDS, FTIR, and UV-vis measurements. And that cyclic voltammogram and EIS studies indicate that the MWCNT/Au heterojunctions have novel electron transfer property, which retard electron transfer of the HRP or the ferricyanide in the underlying electrodes. We believe that the MWCNT/Au heterojunctions with high-stability and unique electrical property are expected to find potential applications for nanodevices.
