1. A method of generating hydrogen gas, comprising:
- providing an aqueous fuel solution comprising a material selected from the group consisting of boranes, polyhedral boranes, borohydride salts, and polyhedral borane salts; and
contacting the aqueous fuel solution with a hydrogen generation catalyst comprising a support, a first metal selected from the group consisting of cobalt, ruthenium, zinc, molybdenum, manganese, titanium, tin, cadmium, and iridium, the first metal being present in an amount of about 0.05 to about 20% by weight of the hydrogen generation catalyst; and
a second metal selected from the group consisting of cobalt, ruthenium, zinc, molybdenum, manganese, titanium, tin, cadmium, boron, and iridium to produce hydrogen gas, the second metal being present in an amount of about 0.01 to about 25% by weight of the hydrogen generation catalyst.

Abstract
Supported catalyst methods are provided to promote hydrogen generation from the hydrolysis of boron hydrides. The methods use a supported catalyst which is a supported metallic mixture comprising a first transition metal selected from the group consisting of cobalt, ruthenium, zinc, molybdenum, manganese, titanium, tin, cadmium, and iridium, in an amount of from about 0.1 to about 20% by weight, and a second metal selected from the group consisting of cobalt, ruthenium, zinc, molybdenum, manganese, titanium, tin, cadmium, boron, and iridium, in an amount of from about 0.05 to about 25% by weight of the supported catalyst.
