A corrosion-resistant RuMoNi catalyst for efficient and long-lasting seawater oxidation and anion exchange membrane electrolyzer
2023
Overview
Direct seawater electrolysis is promising for sustainable hydrogen gas (H
2
) production. However, the chloride ions in seawater lead to side reactions and corrosion, which result in a low efficiency and poor stability of the electrocatalyst and hinder the use of seawater electrolysis technology. Here we report a corrosion-resistant RuMoNi electrocatalyst, in which the in situ-formed molybdate ions on its surface repel chloride ions. The electrocatalyst works stably for over 3000 h at a high current density of 500 mA cm

in alkaline seawater electrolytes. Using the RuMoNi catalyst in an anion exchange membrane electrolyzer, we report an energy conversion efficiency of 77.9% and a current density of 1000 mA cm

at 1.72 V. The calculated price per gallon of gasoline equivalent (GGE) of the H

produced is $ 0.85, which is lower than the 2026 technical target of $ 2.0/GGE set by the United Stated Department of Energy, thus, suggesting practicability of the technology.
Direct seawater electrolysis is promising for sustainable hydrogen production but suffers severe side reactions and corrosion. Here, the authors report a corrosion-resistant electrocatalyst with in situ-formed chloride-ion-repelling cation layer for efficient and long-lasting seawater oxidation.
