Superior electrocatalytic activity of cobalt–nickel oxide nanoneedle films toward oxygen evolution reaction in alkaline electrolyte and alkaline simulated seawater electrolyte

Year: 2026

Type: article

Abstract: -diethyl-1,4-phenylenediamine (DPD) colorimetric method confirmed the absence of the chlorine evolution reaction. The CoNiO-1/NF electrode also exhibited a faradaic efficiency approaching the theoretical limit during the OER in alkaline simulated seawater, reflecting its high selectivity for oxygen evolution. These results highlight its potential as an efficient OER electrocatalyst for seawater-splitting applications.
