Hard template synthesis of metal nanowires
Metal nanowires (NWs) have attracted much attention because of their high electron conductivity, optical transmittance, and tunable magnetic properties. Metal NWs have been synthesized using soft templates such as surface stabilizing molecules and polymers, and hard templates such as anodic aluminum oxide, mesoporous oxide, carbon nanotubes. NWs prepared from hard templates are composites of me...
متن کاملElectrodeposition of Single Crystalline Co56.48Ni43.52 Alloy Nanowires in AAO Template
Single crystalline cobalt nickel (Co-Ni) alloy nanowires are successfully fabricated using direct current (DC) electrodeposition with in the nanopore of highly ordered anodized aluminum oxide (AAO) template. SEM studies show that the average diameter of the alloy nanowires is approximately equal to 50 nm which corresponds to the pore size of the AAO template. Energy-dispersive X-ray (EDX) analy...
متن کاملTemplate-grown metal nanowires.
The growth of metal nanowires using membranes as hard templates is reviewed. The method provides access to arrays of single-crystal metal nanowires and to quasi-one-dimensional metal nanostructures with controlled compositional variation along their length. Recent applications of these kinds of nanowires to problems in superconductivity, optical spectroscopy and sensing, and catalytic conversio...
متن کاملTemplate synthesis of metal nanowires containing monolayer molecular junctions.
Metal nanowires containing in-wire monolayer junctions of 16-mercaptohexanoic acid were made by replication of the pores of 70 nm diameter polycarbonate track etch membranes. Au was electrochemically deposited halfway through the 6 microm long pores and a self-assembled monolayer (SAM) of 16-mercaptohexadecanoic acid was adsorbed on top. A thin layer of Au was then electrolessly grown to form a...
متن کاملSingle crystalline hollow metal-organic frameworks: a metal-organic polyhedron single crystal as a sacrificial template.
Single crystalline hollow metal-organic frameworks (MOFs) with cavity dimensions on the order of several micrometers and hundreds of micrometers were prepared using a metal-organic polyhedron single crystal as a sacrificial hard template. The hollow nature of the MOF crystal was confirmed by scanning electron microscopy of the crystal sliced using a focused ion beam.
