About this collection
We are delighted to share with you a selection of the papers associated with a Faraday Discussion on the chemistry of 2-dimensional materials: beyond graphene. More information about the related event may be found here: http://rsc.li/2dmaterials-fd2020. Additional articles will be added to the collection as they are published. The final versions of all the articles presented and a record of the live discussions will be published after the event.
Graphene has extraordinary chemical and physical properties ensuring its use in opto-electronics, energy and biomedical applications. One of the greatest challenges is to develop and master chemical strategies for other 2D materials such as transition metal dichalcogenides. In nature one can find over 3000 layered compounds with different chemical compositions and structures thereby holding diverse physical properties.
This Faraday Discussion will cover all areas related to other 2D materials' chemistry spanning from their theoretical/computational prediction to their synthesis and functionalization yielding 2D and 3D systems with tailor made physical properties - for composites, foams and coatings, membranes, (bio)sensing, (electro- and photo-)catalysis, energy conversion, harvesting and storage, (opto)electronics, nanomedicine and biomaterials.
