Abstract: The present invention discloses a novel method for the production of metallic nano-powder. This cost-effective, simple process is customized for a full-scale production of metallic nano-powders containing a first metal, and comprising the following of forming an alloy comprising said first metal and at least one soluble metal; applying first thermal treatment in the manner homogenized alloy is obtained; applying a cold work to the homogenized alloy so thin strips are obtained; applying a second thermal treatment to the alloy until a phase composition of predetermined characteristics is obtained; subjecting the said alloy to a leaching agent adapted to effectively leach out the least one soluble metal; filtering and washing the powder; washing the powder; drying the powder; coating the powder with chemicals; and then de-agglomerating the coated powder. The present invention also discloses a cost-effective and highly pure metallic powder produced by the method defined above.

Abstract: A novel method for enhancing the surface area of bulk metals is hereto presented. The method comprising according to one embodiment the steps of dispersing metal nano particles in a solution comprising water-soluble polymeric materials; introducing the a cathode substrate inside the dispersed solution; and than applying electric current to this cathode, so it is coated by said highly dispersed nano particles. According to yet another embodiment the method comprising the steps of coating bulk metals with nano particles made of a predetermined metal alloy; and than chemically leaching at least one of the metals such as a very high surface area of said coated metal is obtained. The present invention also presents bulk metals e.g., electrodes, coated by means of the methods defined above.
