Abstract: Disclosed are systems for producing hydrogen gas and upgrading biomass reactants. The systems are able to couple the oxidation of the biomass reactant to hydrogen gas evolution using catalysts that include a metal component and a non-metal component. Also disclosed are methods of using the systems for producing hydrogen gas and upgrading a biomass reactant.

Abstract: A catalyst, including a conductive substrate coated with a metal-phosphorus-derived film, where the metal is Manganese, Iron, Cobalt, Nickel, or Copper. In some embodiments, the conductive substrate includes copper, titanium, glassy carbon, fluorine-doped tin oxide, indium-doped tin oxide, tin, nickel, or stainless steel. Methods for producing the catalysts and for hydrogen evolution reactions and oxygen evolution reactions employing the catalysts are also described herein.

Abstract: A composition of matter suitable for the generation of hydrogen from water is described, the positively charged cation of the composition including the moiety of the general formula. [(PY5Me2)CoL]2+, where L can be H2O, OH?, a halide, alcohol, ether, amine, and the like. In embodiments of the invention, water, such as tap water or sea water can be subject to low electric potentials, with the result being, among other things, the generation of hydrogen.
