Electrify your chemistry! Pyroelectric heterolayered BiOIO 3 nanoplates efficiently separate photogenerated electron‐hole pairs due to the combined effect of their heterolayered structure and internal polar field (see scheme). Pyroelectric BiOIO 3 nanoplates, synthesized by a simple hydrothermal method, were found to possess a superior photocatalytic activity under UV irradiation.
