Abstract. Atomically thin two-dimensional (2D) materials are a large family of layered materials possesses very diverse properties, covering metals, semiconductors, superconductors, charge density waves, etc. Furthermore, assemble of different 2D materials into heterostructures will generate even more functionalities, making 2D materials and their heterostructures strong candidates for many applications including electronics and electrocatalysis. Scaled up preparation of high quality 2D materials is the first step towards these applications. In this talk, I will present our recent progress on the scaled up preparation of 2D semiconducting transition metal dichalcogenides (TMDCs), semimetallic graphene, as well as insulating h-BN. In addition, I will talk about the use these 2D materials for electrocatalysis based applications, with a focus on large current density hydrogen evolution reactions. Finally, I will discuss our recent progress on the applications of 2D materials for optoelectronicsincluding light detecting and modulation.
