In order to fulfil this goal, three series of (Sb, Sn, Cu)O electrodes with different coke contents were synthetized.

The electrochemical characterization of the synthesized electrodes showed that the coke addition before sintering causes two antagonist effects on the performance of the (Sn, Sb, Cu)O as anodes in electrochemical advanced oxidation processes (EAOP). On one hand, it significantly improves the electrochemical roughness factor of the electrode, solving the densification problem in this way. On the other hand, it worsens the electrochemical behavior of the electrode: narrowing its electrochemical window; and ¿activating¿ it slightly. The addition of coke before sintering changes the kinetic parameters, leading to a kinetic situation in which the accumulation of hydroxyl radicals is slightly lower. A balance must be sought: an intermediate coke content will improve significantly the electrochemical roughness factor of the electrode, but will only worsen slightly its electrochemical behavior, leading to an optimum (Sn, Sb, Cu)O EAOP anode.The authors are very grateful to the Ministerio de Economia y Competitividad (Projects: CTQ2015-65202-C2-1-R and CTQ2015- 65202-C2-2-R) and to the European Regional Development Fund (FEDER), for their economic support.John Wiley & SonsDepartamento de Ingeniería Química y NuclearEscuela Técnica Superior de Ingeniería IndustrialInstituto Universitario de Seguridad Industrial, Radiofísica y MedioambientalGeneralitat ValencianaMinisterio de Economía y CompetitividadRepositorio Institucional de la Universitat Politècnica de València Riunet20192019-05-02journal articlehttp://purl.org/coar/resource_type/c_6501VoRhttp://purl.org/coar/version/c_970fb48d4fbd8a85info:eu-repo/semantics/articleapplication/pdfapplication/pdfhttps://riunet.upv.es/handle/10251/141980reponame:RiuNet.
