Preparation Of Nanostructured Metals And Metal Compounds And Their Uses

摘要

A method for the preparation of materials comprises the steps of: a) taking a first material comprising a compound of a first metal or of a first metal alloy, b) inserting said first material into an electrochemical cell as a first electrode, the electrochemical cell including a second electrode including a second metal different from a metal incorporated in the first material and an electrolyte adapted to transport the second metal to the first electrode and insert it into the first material by a current flowing in an external circuit resulting in the formation of a compound of the second metal in the first electrode material, the method being characterized by the step of treating the first electrode material after formation of the compound of the second metal to chemically remove at least some of the compound of the second metal to leave a material with a nanoporous structure.
