Abstract

This paper discusses our work on the redn. of nitric oxide (NO) by heme groups immobilized on electrode surfaces, which has been conducted in search for selective NO redn. catalysts. Results show two redn. pathways, one leading to the formation of N2O and another leading to the formation of NH2OH. By changing the conditions (pH, potential, NO concn. and immobilization method), 100% selectivity toward either N2O or NH2OH can be obtained. A difference compared to NO reducing enzymes and metals is that immobilized heme groups do not reduce NH2OH further to NH3. Apparently, binding to an isolated heme group is insufficient to break the N-O bond. [on SciFinder (R)]
