| Abstract: |
| Unlike the previous two-step methods, ultrathin TiO2(B) nanosheets were selectively produced via one-step hydrolysis reaction of TiCl3 in ethylene glycol between 140℃ and 180℃ in the present paper. These ultrathin nanosheets have a high activity originating from both the unique open structure that comes from its intrinsic open channels in the lattice and the high surface area. Furthermore, the reaction can be completed in four hours and the solvent, ethylene glycol, can be reused for further synthesis after separating the products by centrifugation. Consequently, it is of potential value to produce the unusual titania nanosheets through this simple, environmentally acceptable and economic approach. |
