Insights into the deactivation mechanism of a self-supported nickel electrode for 5-hydroxymethyl furfural electrooxidation: focus on the stability of the electrode as a whole

Abstract

Three routes were proposed based on the structure of a self-supported NiOx loaded nickel foam electrode under operating conditions, which are: catalytically active layer shedding, nickel matrix dissolution, and the accelerated shedding effect of OER.
