Mechanism of electrocatalytic reduction of nitric oxide on Pt(100)

Article Abstract:

The mechanism of electrocatalytic reduction of nitric oxide on Pt(100)-(1 x 1) in acidic media is studied using voltammetry, in-situ infrared spectroscopy, and on-line mass spectroscopy, considering the effects of surface defects, NO coverage, and the nature of the supporting electrolyte. It is suggested that HNO(sub ads) is the intermediate appearing both in hydroxylamine (HAM) reduction/oxidation and in NO(sub ads) reduction.

Formation and stability of a nitric oxide donor: S-nitroso-N-acetylpenicillamine

Article Abstract:

The formation, reaction dynamics and kinetics and mechanism of the reaction between nitrous acid and N-acetylpenicillamine (NAP) to produce S-nitroso-N-acetylpenicillamine (SNAP) is analyzed in acidic medium. The nitrosation of NAP is accomplished through the direct reaction of nitrous acid with NAP as well as through the formation of the nitrosyl ion, which is abundant only in highly acidic environments.

Effect of pretreatment variables on the reaction of nitric oxide (NO) with Au-TiO2: DRIFTS studies

Article Abstract:

The study examines the effect of the pretreatment on the interaction between NO and Au-TiO2 using DRIFTS as a monitoring tool. It proposes that the (NO)2 species adsorbed to Au sites in different chemical environment are formed and contribute to the observed spectra.
