Thin Layer Sonoelectrochemistry: The Solvents

Year: 2025

Type: article

Abstract: High Resolution Image Download MS PowerPoint Slide In thin layer sonoelectrochemistry (TLS), ultrasound induces constructive interference in a thin fluid layer to increase interfacial rates. In TLS experiments, slow interfacial rates are increased during and after sonication. No cavitation or heating is observed in the fluid. A previously developed model quantifies how solvent properties impact TLS rates. Voltammetry for Fe 3+ and benzoquinone in tetrahydrofuran, dimethylformamide, water, ethanol, and 2-propanol is undertaken with and without sonication. Rate enhancements vary with solvent properties, as quantitatively predicted by the model. The data vet the TLS model for nonaqueous solvents.
