Uniform NH4TiOF3 Mesocrystals Prepared by an Ambient Temperature Self-Assembly Process and Their Topotaxial Conversion to Anatase.

For the first time, we describe a simple, room-temperature surfactant-mediated route to inorganic mesocrystals of NH4TiOF3 and their remarkable topotaxial conversion by washing or annealing to TiO2 as anatase mesocrystals.
