Electrochemical synthesis of porous cobalt nanowall arrays.

Porous cobalt nanowall arrays have been prepared by electrochemical deposition of mono-precursor [Co(NH(3))(5)Cl]Cl(2) on copper substrates. Brunauer-Emmett-Teller (BET) and Barret-Joyner-Halenda (BJH) investigations of the surface properties indicate that the resulting porous nanomaterials possess high surface area and uniform pore size distribution, which implies potential applications in some fields, such as catalysis, energy, and magnetic data storage devices. The magnetism measurements of the porous cobalt nanowall arrays take on a good ferromagnetic behaviour with enhanced coercivity (H(c)).
