Abstract: A novel photocatalyst based on Mn-doped carbon-containing TiO₂ layered metastructure has been successfully prepared. For the first time, the exact distance between layers in highly oriented anatase arrays produced with the assistance of PEG 400 was determined. The synthesis of a series of single-phase Ti_1−xMn_xO₂ samples with a layer-ordered anatase structure and a doping degree from 0.0 to 2.0% was first carried out by annealing crystalline NH₄TiOF₃ together with a Mn- containing precursor in an air atmosphere at 450 °C for 2 h.

Keywords: anatase, mesocrystal, layered structures, photocatalyst, Mn-doped.
