The origin of high electrochemical stability of iridium oxides for oxygen evolution
Yunlong Ding, Wenwen Liu, Zirui Xu, Zhiyao Duan
Abstract
The exceptional stability of IrO 2 is attributed to the highly activated Ir reconstruction due to the inherently stable Ir 4+ in the rutile phase, which hinders the facile water oxidation induced reconstruction mechanism as in Ru dissolution.
