Bioinspired Photoactive Janus-Membranes for Solar to Fuel Conversion (B04)

• Subject Area: Physical Chemistry of Molecules, Liquids and Interfaces, Biophysical Chemistry ; Synthesis and Properties of Functional Materials ; Polymer Materials
• Term: since 2018
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 364549901

B04 will design bioinspired redox-active, polydopamine membranes functionalized with inorganic CdSe@CdS nanorod photosensitizers. The membranes will be used to spatially separate and electronically couple oxidative (focus: WOC/AOC) and reductive (focus: NADR/HER) half-reactions. Membrane design will be used to access asymmetric membranes which act as charge-carrier between both reaction sites, facilitating transfer of electrons and selected chemical species. Optical spectroscopy will be complemented by surface sensitive vibrational sum frequency generation as key mechanistic study tools to elucidate mechanistic details on the light-induced coupled photoreactions.
