讲座摘要：

Soft chemical processes using layered compounds as precursors and topochemical reaction for the structure transformation are unique and useful methods for the developments of functional nanomaterials. The nanocrystal size, crystal facet on surface, morphology, crystal structure, and nanostructure can be controlled using the soft chemical processes. This lecture will give some topics on (1) exfoliation reaction for the syntheses of nanosheets of metal oxides and hydroxides; (2) syntheses of TiO2 nanocrystals with specific facet on surface for photocatalysts and dye-sensitized solar cells from layered titanate nanosheets; (3) syntheses of mesocrystals and mesocrystalline nanocomposites of ferroelectric materials, fabrications of oriented ferroelectric ceramics and films, and their application to high performance piezoelectric materials; (4) ferroelectric semiconductor for perovskite solar cells.
