Electrochemical Characteristics Of Sb Irreversibly Adsorbed On Pt(100), Pt(110), Pt(111) And Pt(320) Electrodes, Yi Yun Yang, Zhi You Zhou, Qi Hui Wu, Shi Gang Sun
Journal of Electrochemistry
The electrochemical behaviors of irreversibly adsorbed antimony on Pt(100), Pt(110), Pt(111) and Pt(320) were studied by using cyclic voltammetry. The results revealeds that the Sb adatoms are stable on Pt(100), Pt(110), Pt(111) and on Pt(320) when electrode potentials are below 0.45 V(SCE) and 0.40 V, respectively. It was demonstrated that various coverages of Sb ad can be conveniently obtained by controlling the number of potential cycling and varying the upper limit of potential scan. The electrochemical behaviors of irreversibly adsorbed antimony varied with the surface atomic arrangement of Pt single crystal electrodes. Based on quantitative results of the relationship between …

Coadsorption Of Para-Toluene Sulfamide And 1.4-Butynediol At Mercury Electrode, Shukun Huang, Naixian Xie, De Gao, Qiang Liu
Journal of Electrochemistry
The coadsorption characteristics of para-toluene sulfamide and 1,4-butynediol atmercury electrode have been studied by means of electrocapillary curve,differential capacity curve,Stuart model and the SCFMO method(CNDO/2).The coadsorption is a physical adsorption occuringnaturally. Lateral and flat orientations in the two adsorbates close to their maximum adsorptionpotential were considered respectively.Unlike attractive interactions of their own,there was arepulsive interaction at their coadsorption layer.A preferred adsorption of 1,4-butynediol occurredWhen they were at the same volume concentration.
