Description de la ressource pédagogique

Description (résumé)

During the past several decades' new carbon allotropes have been accounted for and synthesised. Many notable breakthroughs include exciting works on synthesis, functionalisation, characterisation and applications of carbon nanotubes, graphene, and graphene-like structures, like graphitic carbon nitrides.   The exciting progress made since the initial use of carbons as modifiers of optical semiconductors has stimulated many types of research in different fields of the immediate and relevant application. Apart from the obvious applications in water treatment and remediation, there are compelling examples in photocatalytic synthesis, assisted conversion with the production of valuable chemicals or fuels, photocatalytic production of solar fuels, and photo-assisted purification of compounds of biological and health relevance. Such materials also prompted the development of new integrated and technological solutions, including new photoreactors and combined systems for engineering processes, including microfluidics and additive fabrication. The duality between fundamental and applied, as well as between theory and practice, will be used to present some of our latest progress in the field of conversion of hazardous chemicals in aqueous streams with the in-situ generation of added value compounds, selective photocatalytic synthesis, photo-assisted enzyme purification, and solar fuel production.
