Abstract
Methods and catalysts for oxidizing ammonia to nitrogen are described. Specifically, diruthenium complexes that spontaneously catalyze this reaction are disclosed. Accordingly, the disclosed methods and catalysts can be used in various electrochemical cell-based energy storage and energy production applications that could form the basis for a potential nitrogen economy.
Claims (8)
1. A diruthenium complex having the chemical structure:
wherein:
the central diruthenium is [Ru] 2 n+ , where n is 3-7;
L is NH 3 ;
each E is O;
each X is Cl, F, or Me; and
R is not present.
2. The diruthenium complex of claim 1 , wherein each X is Cl.
