- Аннотация: Templated electrodeposition is a versatile method for preparing metal nanostructures. Among the various parametersof this process, the effect of convection on the deposition process is less explored. The present work isdevoted to the experimental and theoretical study of the influence of natural convection near nanoporous anodicaluminium oxide templates on the deposition of nanowires. Electrochemical deposition of copper nanowires wascarried out with vertical templates parallel to the gravitational acceleration at various overpotentials. A model ofnanowire electrodeposition was developed based on the Navier‒Stokes and diffusion equations. The lengthprofiles of the nanowires, experimentally measured using scanning electron microscopy, were compared with theresults of the numerical simulation. The simulation results were also compared with current-time transientsrecorded during metal electrodeposition into nanopores. In addition, an analytical expression has been proposedto describe the evolution of the deposition current density into nanopores under natural convection conditions.
