Prof. Feng has received numerous accolades, including membership in the German Academy of Sciences and the European Academy of Sciences, as well as being named a Highly Cited Researcher in Chemistry and Materials Science.
Two-dimensional layered materials (2DLMs) , including van der Waals heterostructures (vdWHs), intercalated compounds, and superlattices , represent fundamental building blocks for the next generation of energy devices as well as (opto-)electronic, spintronic, and quantum technologies due to their remarkable chemical and physical properties.
A key challenge in this field is the scalable synthesis of 2DLMs with high purity and tailored functionalities. To address this, we employ wet-chemistry-based approaches, particularly electrochemical intercalation and exfoliation[1] , to synthesize a wide range of 2D materials. An additional advantage of wet chemistry lies in the solution processability of the resulting 2D materials, which enables large-scale device fabrication through various printing technologies, including inkjet and 3D printing.
Among these synthetic routes, electrochemical exfoliation[1] stands out as a promising technique, offering high yield, excellent efficiency, low cost, simple instrumentation, and scalability. By fine- tuning electrochemical parameters, it becomes possible to achieve in-situ functionalization, tunable material properties, and to expand the accessible material library , from graphene to a diverse range of 2D semiconductors[2] , 2D magnets[2] , and beyond.
In this talk, I will take you through our journey , from the early development of electrochemical exfoliation methods for graphene and other 2D materials to their upscaling and integration into electronic, mobility, and energy-storage applications. This research path ultimately led to the establishment of two spin-off companies: one dedicated to the production of 2D materials, and the other focused on developing aqueous zinc-based batteries.
