Electrocatalytic oxidation of ammonia in the neutral ...

A. C. A. De Vooys et al., studied the activity and efficiency of the Pt, Pd, Ru, Rh, Ir, Au, Cu, and Ag electrodes towards ammonia oxidation .They found that transition metals such as Pt, Pd, Ru, Rh, Ir are selective to N 2 formation, while ammonia oxidation on the coinage metals mainly yields complexes M(NH 3) 2 + (M = Au, Ag and Cu). However, efficiency towards selective oxidation of ammonia ...
