“POMbranes” – Incorporation of Catalytically Active Polyoxometalates into Integral Asymmetric Block Copolymer Membranes (B03)

• Subject Area: Inorganic Molecular Chemistry - Synthesis and Characterisation ; Analytical Chemistry ; Polymer Materials
• Term: since 2018
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 364549901

B03 will focus on exploring how molecular light-driven reactivity changes upon matrix integration. The project will study the stability of block copolymer membranes as matrices and assess important reaction parameters under HER and WOC operation conditions. Thereby effects of electrostatic and covalent anchoring of PS and CAT will be explored. The integration of suitable photocatalytically active samples into flow photoreactors will lead to light-driven catalysis under flow, and spatially resolved operando analyses will be performed by X-Ray fluorescence spectroscopy (µ-XRF) and nanopipette electrochemistry. Catalytic performance modification by pore-filling with a pH-responsive hydrogel will be studied.
