Coulostatic potential transients induced by laser heating of platinum stepped electrodes: influence of steps on the entropy of double layer formation

Initial oxidation of silver electrode in weakly acidic sodium fluoride solutions

“…3 shows E vs. t dependences that characterize the changes in the laser heating induced potential shifts as a function of electrode potential. It should be noted that in order to avoid the changes in the measured signal caused by chemisorbed oxygen that appears on the Ag electrode at E ≥ −0.7 V, the transients at E ≥ −0.7 V were recorded immediately after reswitching of the potential from −1.3 V. The trend of these curves as a function of E and t is typical of these signals (see, e.g., [28][29][30][31]), and, in the first approximation, corresponds to negative and positive E values at the negatively and positively charged electrode surface, respectively.

“…These studies were summarized in [28]. Recently, the method of potential shifts induced by laser heating was employed in assessing the zero-charge potentials and the crystal structure of different faces of Au and Pt single crystal electrodes [29,30]. However, the explored potential range did not include the range of oxygen chemisorption where the surface relaxation effects mentioned above could be observed.…”

Towards the understanding of the interfacial pH scale at Pt(1 1 1) electrodes

“…Alternatively, the position of the pzfc can be inferred from indirect measurements, like the reorientation of water dipoles as monitored with infrared spectroscopy [33] or laser inducted temperature jump measurements [34][35][36][37][38][39][40][41]. It is also worth mentioning in this context the studies in UHV of model double layer systems created by sequential dosing of the same components of the true double layer in electrochemical environment [42,43].…”

Thermoelectrochemical study of silver electrodeposition from nitric and tartaric solutions

“…Indeed, greater attention has been devoted to the effects of the heated electrode and its temperature modification, either for stationary or dynamic regimes [5][6][7][8][9][10][11][12][13][14][15][16] by modulating the electrode temperature [10][11][12][13] or using temperature jump techniques [14,15].…”
