Research

Ultrathin nanomaterials, which at least one dimension of the materials is less than 5 nm, or even 2 nm, show amazing size-effects compared to their bulk and traditional nanomaterials. Currently, we particularly devote to studying 1D ultrathin nanowires, and 2D ultrathin nanomaterials.

For 1D inorganic ultrathin nanowires, we explore the synthesis, and polymer-like properties of 1D ultrathin nanowires, and further fabricate 1D ultrathin nanowires based flexible devices.
For 2D ultrathin nanomaterials, we try to develop 2D ultrathin nanomaterial integrated hybrid nanostructures for energy conversion, and storage/conversion, optoelectronics, catalysis, biomedicine.

研究方向：

一维超细纳米线组装、及柔性可穿戴纳米器件（传感、柔性储能等）
二维材料杂化体系构建、及能源存储、光电、催化、生物医药领域应用
