Tuneable supports and geometry effects in SCALMS catalysis (A04)

• Subject Area: Physical Chemistry of Solids and Surfaces, Material Characterisation
• Term: since 2021
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 431791331

Catalysis in SCALMS takes place at the gas/liquid interface. However, standard preparation methods for SCALMS do not control the liquid interface area and, thus, this parameter is mostly unknown, at least under reaction condi-tions. Project A04 targets the preparation and catalytic application of SCALMS materials with ordered, regularly spaced liquid metal droplets of uniform size. For this purpose, dimples (radius of curvature between 10 and 200 nm depending on preparation) will be prepared on planar Al or Ti substrates by anodisation and filled with alloy droplets. Their size will be varied to generate model systems applicable to theoretical description and SCALMS microreactors with optimised specific surface areas.
