Bottom-up synthesis of titanate nanosheets with hierarchical structures and a high specific surface area

The bottom-up synthesis of titanate nanosheets with hierarchical structures and a high specific surface area was described. Anatase nanosheets were obtained from the layered titanate by the removal of ammonia and water in the interlayer spacing at 350°C. The needles were produced under the primary precipitation band through downward growth in the progressive stages of the precipitation. It is expected that the hierarchical architectures of titanate and crystalline titania would be advantageous for a wide variety of practical applications.
