Zr-Doped Ir as an Effective Anode for Refractory SMX Degradation.

ABSTRACT: Electrochemical oxidation has been considered as an efficient method to degrade pharmaceuticals and personal care products. Maintaining low power consumption while increasing the number of oxidation intermediates is deserving of exploring. Herein, Ti/SnO2-Sb/Zr0.3Ir0.7O2 was prepared by Zr doped into IrO2 and used for Sulfamethoxazole (SMX) degradation. The addition of Zr significantly increased the electrochemically active area and facilitated the catalyst to degrade SMX dramatically at a lower overpotential. The extremely outstanding lifetime of catalysts can reach 800 h during the accelerated life test, which showed excellent stability and developmental prospects. The overpotential at 10 mA·cm-2 is about 329 mV, indicating that this electrode has a high oxygen evolution reaction activit
