The “Engine-Shield” strategy: multifunctional cerium hydroxycarbonate encapsulation of iron oxyhydroxide for durable alkaline seawater electrolysis

Key Points

• Alkaline seawater electrolysis efficiency is notably enhanced with the Engine-Shield strategy.
• The encapsulation method involves cerium hydroxycarbonate around iron oxyhydroxide, increasing durability and functionality.
• Observational analysis used a novel encapsulation technique to assess performance under alkaline conditions.
• These findings support the potential of the Engine-Shield strategy for sustainable energy applications.
