Abstract_Claudia Gomes Silva
Graphitic carbon nitride (g-C₃N₄) is a fascinating material that has captured the attention of researchers due to its unique properties and versatility. Its origins trace back to the nineteenth century when Berzelius and Liebig, respectively, reported the general formula (C3N3H)n and coined the notation “melon”.1 This material, obtained by the polymerization of nitrogen-rich precursors like cyanamide, dicyandiamide, or melamine, leading to the formation of a highly ordered polymeric structure, exhibiting remarkable thermal, chemical, and mechanical stability, making it a standout in the realm of advanced materials.2
The rapid advancements in the preparation and characterization of carbon nitride have unveiled its extensive potential for a myriad of applications. Its environmentally friendly and cost-effective synthesis has positioned carbon nitride as an attractive candidate for sustainable technologies. Applications ranging from photocatalysis for fuels and chemicals production to energy storage and electronic devices have demonstrated the versatility and significance of this remarkable material. Furthermore, its use in environmental remediation and biomedical applications continues to expand the frontiers of its utility.
This talk will present several approaches for boosting the activity of g-C3N4 for applications ranging from photocatalytic synthesis of aldehydes and imines, to hydrogen and hydrogen peroxide production and wastewater treatment.3,4,5 Furthermore, its utilization in biomedical applications will also be discussed. The use of such materials in structured photoreactors, seeking process intensification, will be discussed.6,7
