Constructing a dual-protection heterointerface for durable anion exchange membrane seawater electrolysis at ampere-level current density

Key Points

• To enhance the durability of metal catalysts against chloride ion corrosion during seawater electrolysis for hydrogen production.
• Developed a dual-protection heterointerface for metal catalysts.
• Conducted seawater electrolysis experiments at ampere-level current density.
• Evaluated the performance of catalysts under corrosive conditions.
• The dual-protection interface significantly reduced corrosion of metal catalysts.
• Sustained hydrogen production was achieved at increased current densities for extended periods.
• Improved durability indicates potential for sustainable hydrogen production using seawater.
