Development of Carbon-ZrO2 composites with high performance as visible-light photocatalysts Bailón García, Esther Elmouwahidi, Abdelhakim Carrasco Marín, Francisco Pérez-Cadenas, Agustín F. Maldonado-Hódar, Francisco J. Mesoporous carbon-ZrO2 composites (CZrX) were successfully synthesized by a direct sol-gel procedure. A large battery of experimental techniques is applied for sample characterization. ZrO2 nanoparticles were homogeneously distributed on the carbon supports and stabilized in the cubic phase. The interactions between organic-inorganic phases determine the formation of non-stoichiometric ZrOx oxides, the reduction of the ZrO2 band-gap values and the charge carriers’ recombination, favouring the absorbance of visible light and the photocatalytic behaviour. The total mineralization ofthe dye and the simultaneous reduction of the toxicity are achieved. 2025-01-28T10:46:42Z 2025-01-28T10:46:42Z 2017-05-30 journal article Applied Catalysis B: Environmental 217, 2017, Pages 540-550 https://hdl.handle.net/10481/100718 https://doi.org/10.1016/j.apcatb.2017.05.090 eng http://creativecommons.org/licenses/by-nc-nd/4.0/ open access Attribution-NonCommercial-NoDerivatives 4.0 Internacional
