ABSTRACT:
Metal hydrides are activated by an electrochemical procedure. In this procedure, a bulk sample of the corresponding metal is immersed in an aqueous electrolyte and contacted by a cathode. Current passed through the aqueous electrolyte causes electrolysis of the water and a concomitant reaction with the formation of metal hydride. As a result, the metal hydride is fractured and smaller particles result. Additionally, the resulting metal hydride has a substantial amount of absorbed hydrogen. A novel plating method, taking advantage of the reducing power of hydrogen absorbed in a metal hydride, is useful to encapsulate such metal hydride with a variety of metals. Therefore, such hydrides are uniformly coated by using plating solutions without the standard reducing agent and stabilizer.
