Concluding remarks: Chemistry of 2-dimensional materials: Beyond graphene

Since graphene was exfoliated in 2004, two-dimensional (2D) materials have received great attention due to their physical and chemical properties associated with their nanosized thickness and the correlated quantum size effect. 2D planes allow the confinement of charge carriers, heat, and photons, leading to the remarkable electronic and optical properties of these materials. The Faraday Discussion "Chemistry of 2-dimensional materials: beyond graphene"has been an incredible showcase for a variety of highly interesting contributions in the field. This conference comprised a large number of aspects of the topic: from their synthesis and the study of their optical and physical properties to their numerous applications. These concluding remarks aim to capture the recent developments in 2D materials chemistry and physics that were presented and debated during this Faraday Discussion, and more generally in the research field in recent years. Particular attention will be paid to aspects like the synthesis of the materials, their toxicity and biodegradation, and some of their major applications in catalysis, as well as Li-ion batteries, water filtration and sensing. In addition we aim to highlight future challenges that still need to be addressed.
