Carbon dots on TiO2 for perovskite photovoltaics, methanol oxidation and water splitting

Talk delivered in 7th International conference on Advanced Hydrogen Energy, ANM conference series 2019, at University of Aveiro, in Aveiro, Portugal, 17-19 July 2019.- 1 FiguraCarbon dots (CDs) are a class of fluorescent nanoparticles including an extremely rich variety of structures and functional groups. Interestingly, not only the physicochemical properties are affected by the nature of the CD structure, but also their optical behavior. Fluorescence in CDs shows particular characteristics of strong intensity and wavelengths in the visible region. Consequently, an interesting issue arises on how structurally-different CDs modify the electron transport and photoactivity of semiconductor oxides, in particular TiO2.This work has been funded by the MINECO and the European Regional Development Fund (ENE 2016-79282-C5-1-R), the Government of Aragón (T03-17R and E14-17R), and the European Commission (H2020-MSCA-ITN-2014-ETN 642742 “Enabling Excellence”).Peer reviewe
