Lecture Title:2D Colloidal Semiconductors and Their Derived Hybrid Nanostructures: Synthesis, Properties and Applications

Dr.Xue-Jun Wu

Abstract

Along with layered graphene and transition metal dichalcogenides (TMDs) with intrinsically layered crystal structures, two-dimensional (2D) semiconductor nanostructures have been emerging as an important class of nanomaterials because of their unique optical and electrical properties and various potential applications in optoelectronic devices and photocatalysts. In this talk, I would like to briefly summarize the challenges and opportunities on the wet chemical approaches for the synthesis of the 2D semiconductor nanostructures. Next, I will highlight our recent research achievements on the controlled synthesis of 2D colloidal semiconductorswith a variety of compositions, from binary to ternary or even quaternary compounds. Also, I would like to show the extraordinary hybrid nanostructures based on the colloidal semiconductor nanoplates and their application in photocatalytic hydrogen evolution. Finally, I will brief discuss our future directions.
