Importance of Electrode Tailoring in the Coupling of Electrolysis with Renewable Energy

In this work, it has been evaluated how the performance of an electrolyzer, used to treat a clopyralid waste and directly powered without regulation by a battery, is influenced by the electrodes resistance. Electrolyzers were equipped with electrodes consisting of the same boron-doped diamond (BDD)...

Los electrolizadores estaban equipados con electrodos que consistían en el mismo recubrimiento de diamante dopado con boro (BDD) depositado en diferentes sustratos (Si, Ta y Nb). Los resultados exponen grandes diferencias a pesar de utilizar el mismo recubrimiento. Se lograron velocidades de eliminación más rápidas con electrodos de Ta- y Nb-BDD. La cantidad de energía requerida para lograr la misma eficiencia de remoción mostró grandes diferencias. Se eliminaron hasta 1,95 mg/Wh de pesticida al usar Si, en comparación con 2,14 mg/Wh eliminados con Ta. Además, la cantidad y la fuerza de los oxidantes generados también fueron bastante diferentes. 86. Se necesitaron 78 mmol de oxidantes para eliminar un gramo de plaguicida con Ta-BDD y 30,57 mmol con Si-BDD. Por lo tanto, la resistencia de los electrodos es un aspecto importante que se debe considerar para lograr un diseño adecuado de sistemas de almacenamiento de energía que permitan la alimentación fotovoltaica verde de tecnologías electroquímicas utilizando baterías convencionales como refuerzo para garantizar una operación continua.Wiley202220222020info:eu-repo/semantics/articleapplication/pdfapplication/pdfhttp://hdl.handle.net/10578/30062reponame:RUIdeRA.
