Validating Electrochemical Active Surface Area Determination of Nanostructured Electrodes: Surface Oxide Reduction on AuPd Nanoparticles
Cignoni, P., Hosseini, P., Kaiser, C., Trost, O., Nettler, D., Trzebiatowski, L., Tschulik, K., Journal of The Electrochemical Society2023, 1945-7111 In our new Journal of the Electrochemical Society publication, we describe a new approach to validate ECSA determination techniques to nanoparticles. We use this approach to determine correct experimental condition to investigate Au-Pd nanoparticles ECSA by surface oxide reduction. Read the full article...

Impact of the Electrochemically Inert Furan Ring on the Oxidation of the Alcohol and Aldehyde Functional Group of 5-Hydroxymethylfurfural (HMF)
Sobota, L., Bondue, C. J., Hosseini, P., Kaiser, C., Spallek, M., Tschulik, K., ChemElectroChem2023, e202300151 In our new ChemElectroChem article, we use the example of 5-hydroxymethylfurfural to show how individual functional groups of organic molecules influence reactivity. The presence of a furan ring in a molecule increases the reactivity of aldehyde and alcohol oxidation by increasing the adsorption strength due to the ring. However, the activity of alcohols and aldehydes remains unaffected by a furan ring. Read the full article...
