A hollow cage-like layered double hydroxide-modified carbon paste electrode as an efficient catalyst for electrochemical water oxidation in neutral media

Abstract

We fabricated a hollow cage-like layered double hydroxide modified carbon paste electrode (Ni₁Co₄-LDH/C) as an efficient catalyst for electrochemical water oxidation in neutral media. Reaction kinetics studies indicate that Ni₁Co₄-LDH/C can provide high water oxidation performance, mainly due to the small charge transfer resistance, and a high number of catalytic active sites.
