“…In addition, a pair of broad peaks for MEA-7800 sit at the potential range of around 0.6 Ve1.0 V vs. SHE. Particularly, the anodic peak of MEA-7800 localizes 0.78 Ve1.1 V vs. SHE, and the peak is approximately horizontal, which is attributed to the Ir(III)/Ir(I) and Ir(V)/ Ir(VI) redox surface transition [26]. An increase of the peaks of Ir(III)/Ir(IV) and Ir(V)/Ir(VI) redox surface transition is observed after 7800 h, which may be attributed to an increase of the number of active surface sites.…”

“…As propriedades mecânicas, elétricas e catalíticas dos ADEs são de grande interesse científico e muitas questões relacionadas aos mesmos requerem um entendimento mais aprofundando. Sendo assim, tem-se um número elevado de trabalhos abordando estudos cinéticos e as aplicações destes eletrodos em reações de oxidação de cloro (RDCl) 24,39,41 , oxigênio (RDO) 13,36,38,40,45,47,48,51,53 e oxidação de moléculas orgânicas 15,44,60,66,[69][70][71] .…”
