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 Society 2023, 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.

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., ChemElectroChem 2023, 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.

Electrochemical Aldehyde Oxidation at Gold Electrodes: gem-Diol, Non-Hydrated Aldehyde and Diolate as Electroactive Species

Bondue, Christoph Johannes, Spallek, Marius, Sobota, Lennart, Tschulik, Kristina, ChemSusChem 2023, e202300685
In our new ChemSusChem article, we identify the electroactive species of aldehydes. Next on the list: exploiting this to avoid the decomposition of aldehydes in the electrochemical upgrading of biomass.

The involved devices of the different liquid diagnostics are marked by different frames: solid: spectrophotometric approach using ammonium metavanadate; dashed: terephthalic acid dosimeter; and dashed-dotted: detection of chemiluminescence of luminol. iCCD, intensified charge-coupled device. LDLS, laser driven light source.
