Abstract Scope Recently, two dimensional ferroelectric (2DFE) materials (monolayers exhibiting spontaneous switchable electric polarizations) have been gaining attention for ultrathin electronics. However, few such compounds exist, and even fewer that have out-of-plane polarizations. In this work, we performed high throughput density functional theory (DFT) calculations on materials from the 2DMatPedia database to discover new 2DFEs. Furthermore, we investigated the potential for 2DFEs to be used in photocatalysis, as the asymmetry in the surface electron density on a poled up versus poled down configuration could allow for the dynamic tuning of reactivity via polarization switching. Specifically, we focused on the photoreduction of CO2 to C1 products, as there are numerous competing products. We found that switching the polarization in Y2CO2, a 2DFE MXene, can preferentially stabilize the adsorption or desorption of different reactants or products and the stabilization of different intermediates, thereby tuning the selectivity for different C1 products.
