Plated Cobalt-boron Catalyst on High Surface Area Templates for Hydrogen Generation from Sodium Borohydride
The invention provides a catalyst-coated nickel template including a) an open-cell nickel foam having within it pores defined by an internal nickel surface, the foam also having an external nickel surface not within the pores; and b) a layer of catalyst including Co and B on at least a portion of the internal nickel surface and at least a portion of the external nickel surface. The invention also provides a method of making a catalyst-coated nickel template that includes contacting a nickel template with a solution including a cobalt salt, a complexing agent, and a boron source selected from organoboranes and organoamine boranes under conditions sufficient to deposit boron and cobalt on a surface of the nickel template. Methods of generating H2 at a predetermined rate include contacting a NaBH4 solution with the catalyst-coated nickel template.
