Electrocatalysis under confinement: Carbon dioxide reduction with COF catalysts
This project aims to understand, model and control confinement effects on the electrocatalytic CO2 reduction reaction (CO2RR) in the atomically precise pores of covalent organic frameworks (COFs). We will integrate COF design, advanced electrochemistry and theoretical modelling in a tight feedback loop to arrive at a fundamental understanding of CO2RR reactivity under confinement. Confinement effects to be studied include (i) CO2 capture and oversolubility in mesopores, (ii) increase of CO2RR vs. hydrogen evolution reaction selectivity via control of the local pH, mass transport and electrochemical double layer, and (iii) selectivity enhancement for multicarbon (C2+) products by tandem catalysis.
Research focus in the first funding period (2018-2022):
Covalent organic frameworks as tailored substrates with molecularly defined pores for molecular heterogeneous catalysis.
