Electrochemical deposition of metals from hexagonal lyotropic liquid crystalline phases produces metal films with a unique ordered nanostructure in which the cylindrical pores of 1.7 to 3.5 nm running through the film are arranged in hexagonal arrays. Nanostructured Pd films were deposited electrochemically from the template mixture of either C16EO8 or Brij 56. Electrochemical studies showed that the metal films have a high electroactive surface area. These values together with the TEM and X-ray data are consistent with the expected nanostructure. Adsorption characteristics of deuterium on the Pd metal surface are slightly different than those obtained for hydrogen in previous studies. Diffusion of deuterium into the Pd metal lattice works with fast kinetics under appropriate surface modification. This paper highlights the research on the nanostructured palladium deuterium system outlining the kinetic behaviour of deuterium diffusing into the pores of the nanostructure. To our understanding, this kinetic aspect is believed to be the key issue to achieve nuclear reactions within metals of any choice.
