Design of a Multilayered Oxygen-Evolution Electrode with High Catalytic Activity and Corrosion Resistance for Saline Water Splitting

Jihong Li et al.

Summary: This study reported the design of a multilayered oxygen-evolution electrode synthesized through direct thermal boronization to meet the requirements of seawater electrolysis. The electrode consists of an oxidized NiFeBx alloy layer, a NiFeBx alloy interlayer, and a NiFe alloy substrate, which are conductive to the generation and stabilization of the catalytic active phase gamma-(Ni,Fe)OOH.

The Critical Role of Additive Sulfate for Stable Alkaline Seawater Oxidation on Nickel-Based Electrodes

Tengfei Ma et al.

Summary: The addition of sulfate in the electrolyte can effectively retard the corrosion of chloride ions to the anode, greatly improving corrosion resistance and prolonging operating stability of nickel foam. The theoretical simulations and in situ experiments demonstrate that sulfate anions can form a negative charge layer on the anode surface to repulse chloride ions by electrostatic repulsion.

Seawater electrocatalysis: activity and selectivity

Sakila Khatun et al.

Summary: Seawater is considered a major hydrogen reservoir, but the presence of multielements and interference in electrochemistry, particularly chlorine chemistry, make electrocatalytic water splitting challenging. To achieve sustainable seawater electrolysis, focus should not only on electrocatalyst activity but also on selective oxygen evolution reaction to suppress corrosive chlorine chemistry.
