Abstract

Ni2+ ions in aqueous solutions were electrochemically deposited within pores of alumina compacts attached to carbon or Pt electrode at room temperature. The deposition behavior of Ni metal in the pores of alumina compacts was expressed by an empirical power law equation of W = ktn, where W is the weight of Ni deposited, k the deposition rate constant, t the deposition time, and n the experimental constant (0.52-0.56). The shape of Ni deposited was dependent on the geometry of positive electrode.
