“…Note that such a thiolate/copper structure can be called a coadsorption structure, and examples like I/Ag/Pt(lll), detected after electrodeposition of silver on I/Pt(lll) (not adsorption of iodide on Ag/Pt(lll)!) are well documented [33,34,73]. The question we have to address is whether copper atoms can penetrate a thiolate layer; in section 4.4 we will show that this is indeed possible.…”

We have investigated the structure and thermal dynamics of alkanethiolate layers on Au(lll) with variable temperature scanning tunnelling microscopy (STM), X-ray photoelectron spectroscopy (XPS) and voltammetry. The results build the basis for a study of electrodeposition of copper on alkanethiolate-covered Au(lll). Electrodeposition has been studied as a function of the thiolate chain length, the deposition potential and the temperature. Time-resolved [1][2][3][4][5][6][7].

“…High temperature dosing of halogènes can even produce virtually defect-free surfaces [2,73] as can prolonged annealing of thiolate-covered Au(lll) [42]. For this annealing procedure, the vacancies and step edges move by diffusion of single substrate atom vacancies [26,45].…”

“…3 shows stripping voltammograms of poison produced on rotating Pt electrodes at 0.13 V under a chronoamperometric condition. Specifically, an iodine solution (~0.1 mL) of 0.1 M was injected into a formic acid solution (~100 mL) at 2400 sec after a potential jump from −0.23 V to 0.13 V. The injected iodide adsorbs bare Pt sites without replacing the already existing poison to prevent further adsorption of formic acid [11,12], so that the oxidation of formic acid was completely prevented as exemplified by the sudden current drop at 2400 sec in Fig. 2(a).…”

This work presents the variation of formic acid oxidation on Pt depending on hydrodynamic condition using a rotating disk electrode. As the rotating speed increases, the oxidation rate of formic acid decreases under voltammetric and chronoamperometric measurements. The coverages of poison formed from formic acid during the chronoamperomertric investigations decrease when the rotating speed increases. As the roughness factor of Pt electrode surface increases, on the other hand, the current density of formic acid oxidation increases. These observations are discussed in terms of the tangential flow along Pt electrode surfaces generated by the rotating disk electrode, which reduces a contact time between formic acid and a Pt site, thus the formic acid adsorption.

An indirect method for determination of atmospheric sulfur dioxide was developed and tested. Air samples were collected in 30 % H 2 O 2 solution which converts SO 2 to SO 2À 4 . The sampling technique is the same technique used in the thorin spectrophotometric method for analysis of sulfur dioxide. The developed method, however, relied on voltammetric analysis of Pb(II) upon addition of an excess Pb(II) solution. The excess Pb(II) was determined by linear sweep anodic stripping voltammetric analysis at an iodine-coated polycrystalline platinum electrode. The electrode iodination was carried out from the gas phase. The calibration plot from cyclic voltammetric measurements of the cathodic deposition peak current and the Pb(II) concentration showed a remarkable linearity between the peak current and Pb(II) concentration (correlation coef®cient 0.9994). Stripping analysis of Pb(II) at the iodine-coated electrode showed better sensitivity and excellent linearity between the anodic stripping peak current and the concentration of Pb(II) (correlation coef®cient 0.9934). Application of voltammetric analysis for the indirect determination of SO 2 also showed remarkable linearity and a sensitivity not less than that of the thorin method (R 0X9993). The developed method passed the recovery and real-life analysis tests.
