BSA 12-28: Non-Noble Metal Water Electrolysis Catalysts

This invention comprises an inexpensive catalyst system for water electrolyzers by replacing the noble-metal catalysts that are typically used in electrolyzer systems. A molybdenum-nickel nitride nanosheet catalyst has been found to be very stable
Patent Abstract: 
A novel form of nickel-molybdenum nitride - nanosheets - has been found to be a highly effective catalyst for splitting water to form hydrogen gas. The combination of reactive Ni with electron-dense Mo and its conversion to the nanosheet nitride form has produced a durable and highly active hydrogen evolution catalyst. Nitrides of other metals in combination with molybdenum are expected to have comparable activity.
Benefits 
The majority of the cost of current electrolyzers is a result of the requirement for use of noble-metal catalysts, particularly platinum. Replacement with considerably less expensive catalysts that are highly active and stable can result in new electrolyzers at a lower cost.
