Two widely available green organicprecursors, the Argentinean herb Mate and the Stevia plant have been selected as the carbogenic sourceto thermally induce the formation of different types of CNDs with different levels of N and P doping andtunable photoluminescence response in the UV–vis-near infrared (NIR) ranges. These CNDs have beensuccessfully assembled with TiO2to form heterogeneous photocatalysts that are highly active in thevisible-light and NIR- driven photodegradation of 2,4-dichlorophenol (2,4-DCP), a persistent chlorinatedorganic compound present in numerous pesticide formulations.2017http://zaguan.unizar.es/record/7084210.1016/j.apcatb.2017.06.021http://zaguan.unizar.es/record/70842oai:zaguan.unizar.es:70842info:eu-repo/grantAgreement/ES/MINECO/MAT2016-79776-Pinfo:eu-repo/grantAgreement/EC/FP7/312483/EU/Enabling Science and Technology through European Electron Microscopy/ESTEEM 2info:eu-repo/grantAgreement/EC/FP7/294094/EU/Synthesis and characterization of NANOstructured materials with LumInescent properties for diaGnostic and tHerapeuTic applications/NANOLIGHTinfo:eu-repo/grantAgreement/EUR/ERC/HECTOR-267626info:eu-repo/grantAgreement/ES/DGA/E26APPLIED CATALYSIS B-ENVIRONMENTAL 218 (2017), 68-79by-nc-ndhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/info:eu-repo/semantics/openAccess
