Photoactive Nanofibers as Materials for Light-driven Catalysis (B11*)

• Subject Area: Inorganic Molecular Chemistry - Synthesis and Characterisation ; Physical Chemistry of Molecules, Liquids and Interfaces, Biophysical Chemistry
• Term: since 2022
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 364549901

B11 develops electrospinning methods for the design of nanofibers and self-supporting nanofiber mats based on functional polymers with embedded molecular PS and CAT species (focus: HER and WOC). Surface and pore engineering of the nanofiber will be used to facilitate mass transport and light-penetration as well as gaseous product release. As second-generation nanofibers, core-shell structures featuring a light-absorbing core and catalytic protective shell will be designed using coaxial electrospinning methods. The effects of polymer integration on the photophysical properties and catalytic reactivity of the molecular components will be studied using in situ time-resolved spectroscopic methods. This will provide mechanistic understanding of the processes which control light-driven reactivity in nanofibers.
