报告内容简述：

Two dimensional (2D) inorganic nanosheets offer exciting opportunities for fundamental studies and many technological applications due to their unique and fascinating physical and chemical properties. Preparation of 2D materials via exfoliation/delamination from intrinsically layered materials or controlled growth from intrinsically non-layered materials has been a key topic. 2D energy materials have proven effective in constructing kinetically favorable ion channels, but the irreversible restacking of the individual 2D nanosheets during materials processing or device fabrication may lead to the decrease of active sites for ion storage and the sluggish ion transport. In this talk, I will first discuss the research progress of rational synthesis of 2D nanomaterials and their applications in energy storage in Yu research group in UT-Austin. Then I will also discuss the possible strategies developed in Yu Group to possibly release the restacking problem of 2D nanosheets, including interlayer engineering and pore engineering in 2D nanosheets.
