In article number 2003548, Peter V. Sushko, Dongsheng Li and co‐workers report an atomic defect‐free gradient structure that extends across the bulk of anatase crystals, creating a 3D internal electric field that enables an up to 100% fraction of photo‐active volume, and leads to anomalously efficient electron‐hole separation across the bulk material and thus, substantially higher photoactivity than standard anatase crystals.
