The proposed international collaboration will develop fundamental understanding of the coupling between selective transport and reaction phenomena in nanoporous materials for sustainable energy technologies. The project will devise and demonstrate an innovative electrochemical model setup to achieve unique control over the nanoporous geometric specifications and the local reaction environment (LRE) for transport and reaction in the nanoconfined region. It will harness closely integrated efforts in theory, simulation, and experimental approaches. The proposed system consists of anodized aluminium oxide (AAO) with highly ordered cylindrical nanochannels. The electrolyte-filled nanochannels are contacted by electrode layers applied to both sides of the AAO membrane, with one of them (WE 1) referred to as the substrate electrode and the other (WE 2) acting as the gate electrode. We will specifically exploit this model system for two experimental modes: (1) Pump–Probe where a time-dependent perturbation of the LRE is generated at WE 1 and propagates along the nanochannel to be probed at the WE 2. (2) Gate–Read-out where ion transmission across WE 2 into the nanochannel is selectively controlled by the gate electrode potential and the activity and selectivity are read out and assessed at WE 1.
