摘要：

The reductive electrochemistries of both [Ru(II)(Hedta)(NO+)]0 and [Fe(II)(Hedta)(NO*)]- have been investigated as a function of pH. The nitrosyl complexes are effective electrocatalysts for the reduction of NO2- or HONO to give the reduced products N2O, N2, NH3OH+, or NH4+. An element of product selectivity is available by making appropriate choices in pH, applied potential, or catalyst. The mechanisms by which nitrite is reduced appear to be similar to those identified earlier for polypyridyl complexes of Ru and Os and for water-soluble porphine complexes of Fe.
