Anodic abatement of glyphosate on Pt-doped SnO2 Sb electrodes promoted by pollutant-dopant electrocatalytic interactions

[EN] The development of non-expensive and efficient technologies for the elimination of Glyphosate (GLP) in water is of great interest for society today. Here we explore novel electrocatalytic effects to boost the anodic oxidation of GLP on Pt-doped (3-13met%) SnO2-Sb electrodes. The study reveals t...

Here we explore novel electrocatalytic effects to boost the anodic oxidation of GLP on Pt-doped (3-13met%) SnO2-Sb electrodes. The study reveals the formation of well disperse Pt nanophases in SnO2-Sb that electrocatalyze GLP elimination. Cyclic voltammetry and in-situ spectroelectrochemical FTIR analysis evidence carboxylate-mediated Pt-GLP electrocatalytic interactions to promote oxidation and mineralization of this herbicide. Interestingly, under electrolytic conditions Pt effects are proposed to synergistically cooperate with hydroxyl radicals in GLP oxidation. Furthermore, the formation of by-products has been followed by different techniques, and the studied electrodes are compared to commercial Si/BDD and Ti/Pt anodes and tested for a real GLP commercial product. Results show that, although BDD is the most effective anode, the SnO2-Sb electrode with a 13 met% Pt can mineralize GLP with lower energy consumption.The authors gratefully acknowledge the EDGJID/2021/330 contract (Generalitat Valenciana, Spain), as well as the RYC-2017-23618 contract and TED2021-131028B I00 project funded by MCIN/AEI/10.13039/ 501100011033 and ESF Investing in your future and European Union NextGeneration EU/PRTR .ElsevierDepartamento de Ingeniería Textil y PapeleraEscuela Politécnica Superior de AlcoyEuropean CommissionGeneralitat ValencianaAgencia Estatal de InvestigaciónMinisterio de Economía y CompetitividadRepositorio Institucional de la Universitat Politècnica de València Riunet20242024-01-01journal articlehttp://purl.org/coar/resource_type/c_6501VoRhttp://purl.org/coar/version/c_970fb48d4fbd8a85info:eu-repo/semantics/articleapplication/pdfhttps://riunet.upv.es/handle/10251/220612reponame:RiuNet.
