Orient express: Ultrathin nanosheets of bismuth tungsten oxide (Bi 2 WO 6 ) with {001}‐orientation are prepared by a pH‐controlled synthesis. The sheets have aspect ratios as large as 30:1, and offer superior adsorption and hole oxidation properties as well as prolonged charge‐carrier lifetimes.The ultrathin structures show enhanced photocatalytic activity towards organic contaminant degradation and water oxidation.
