Comparative Evaluation of Dimethylsulfoxide and Dimethylsulfone Adsorption on a Smooth Platinum Electrode in Acidic Environment

Nonaqueous Solvent Adsorption on Transition Metal Surfaces with Density Functional Theory: Interaction of N,N-Dimethylformamide (DMF), Tetrahydrofuran (THF), and Dimethyl Sulfoxide (DMSO) with Ag, Cu, Pt, Rh, and Re Surfaces

“…To this end, experiments have been carried out to investigate the interactions of these solvents with metal surfaces. Electrochemical studies have indicated that solvents interact with transition metal surfaces, affecting fundamental electrochemical properties and the rates of reactions at these electrodes. − Different solvents, such as DMSO, DMF, and THF, have distinct and electrode-dependent effects on the potential of zero charge (PZC), capacitance, and other fundamental surface electrochemical properties. ,− Differences in PZC and capacitance among different solvents, and metals, originate at least in part from differences in metal–solvent interactions, including possible chemisorption and its effect on interfacial solvent orientation. ,,− Spectroscopic experiments − have also been used to study solvent–metal interactions. For example, spectroscopic evidence indicates a strong chemisorption of DMSO on Pt, and also significant interaction with Au , and Ag, displaying preferential adsorption to step sites .…”
