“…The mechanism underlying the enhanced Pt dissolution in the presence of NaNO 2 is not completely understood. It was reported that nitrogen oxides such as NO, NO 2 , and N 2 Osome of them are included in the reduction products of HNO 2 were able to function as complexing agents for Pt; , thus, the nature of the dissolved species requires further investigation.…”

To elucidate the mechanism of NaNO2-promoted Pt dissolution, the weight loss of Pt black-deposited Au quartz resonators was measured in 0.1 mol dm–3 HClO4 containing NaNO2 under potential cycling and constant potential conditions. A continuous weight loss of ca. 50–60 ng cm–2 cycle–1 was detected in the presence of 10 mmol dm–3 NaNO2 during potential cycling above a high potential limit of 1.2 V vs RHE (VRHE) and below a low potential limit (E L) of 0.9 VRHE. A weight loss was observed at constant potentials (0.6–0.8 VRHE) when oxides were initially present; the net weight loss (Δw) magnitude increased as the amount of the initially formed Pt oxide increased. These results indicate that Pt dissolution occurred when Pt oxides were reduced in the presence of NaNO2. The good agreement between the Δw per potential cycle and the Δw at a constant potential (E L of the potential cycling = constant potential) revealed that the formation of Pt oxides in the positive sweep was required for the continuous weight loss under potential cycling. The Δw value increased for higher concentrations of NaNO2 under both conditions. The products of NaNO2 reduction were thought to participate in Pt dissolution.

Modern NMR based methods of studying the kinetics and mechanisms of reversible photo chemical reactions in solutions are surveyed. Detailed consideration of peculiar features of the experimental techniques based on NMR lineshape analysis and double resonance NMR and used for the determination of the effective rate constants for and quantum yields of photo induced chemical exchange processes is presented.
