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

Abstract

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 electro- des consisting of the same boron-doped diamond (BDD) coating deposited on different substrate (Si, Ta and Nb). The results expose great differences despite using the same coating. Faster removal rates were attained with Ta- and Nb-BDD electrodes. The amount of energy required to attain the same removal efficiency showed great differences.
