Efficient Regeneration of Partially Spent Ammonia Borane Fuel

Going full circle: Ammonia borane is a potential H2‐releasing fuel. Polyborazylene, a form of the spent fuel, can be regenerated efficiently in a one‐pot process by the stepwise addition of appropriate digesting and reducing agents. A unique feature of this process is the formation of NH3, which is...

Summary:Going full circle: Ammonia borane is a potential H2‐releasing fuel. Polyborazylene, a form of the spent fuel, can be regenerated efficiently in a one‐pot process by the stepwise addition of appropriate digesting and reducing agents. A unique feature of this process is the formation of NH3, which is retained by some of the digested species.
