摘要：

An anodic voltammetric wave of NO catalyzed by meso-tetra(N-methyl-4-pyridyl) iron(III) pentachloride ([Fe-III(TMPyP)](5+)) was found in a phosphate buffer solution (pH 7.4). The current was 10 times larger than the diffusion-controlled current of NO without the iron porphyrin. The current can be used to detect NO in aerobic physiological environments. Spectroelectrochemical measurements suggested the formation of iron-nitrosyl complex, which is responsible for the catalytic oxidation of NO. The intermediate of the catalytic oxidation was detected by spectroelectrochemistry. (C) 1999 Elsevier Science S.A. All rights reserved.
