We produce nanostructured thin films of a range of photocatalytic materials for use in photoelectrocatalysis (PEC), with a particular focus on using the in-built polarisation of ferroelectric materials to enhance charge separation and therefore catalytic activity. We have previously demonstrated this using the powdered photocatalyst BaTiO3, showing that ferroelectricity produces a substantial enhancement of photocatalytic activity.
