The method of obtaining Ni and Co nanowires in porous anodic alumina matrices

This paper focuses on the investigation of producing Ni and Co nanowire arrays synthesized using Al₂O₃ porous template. Porous alumina samples were obtained by double electrochemical anodizing of the prepared foil in 0.5 M  oxalic acid, at a voltage of 60 V and a temperature of 25 °C. The pore diameter distribution maximums are about 85 nm. Nanowires were electrodeposited in a 3-electrode electrochemical cell into prepared matrices in a potentiostatic and galvanostatic mode. Studies of the surface of porous membranes and the geometry of nanowires were carried out using scanning electron microscope.
