Abstract:
Using a simple two-stage method including the electrochemical synthesis of Ni nanotubes in the pores of
PET membranes and their coating with gold or platinum, nanotubes with a structure of the «magnetic core – noble metal
shell» type have been synthesized. The morphology of the coating is a thin continuous film with growths of various shapes.
X-ray diffraction analysis estimated separate phases of nickel (core) and noble metal (coating). The magnetic properties
of coated nanotubes do not differ significantly from the properties of the initial nanotubes. The method allows one to synthesize structures such as one-dimensional nanostructures of the «magnetic core – noble metal shell» type for use in the detection
of chemical and biological compounds, as magnetic carriers for the delivery of drugs and genes, which can also be used as
multicyclic catalysts on a magnetic carrier.
