Abstract Seawater electrocatalysis is urgently needed for various energy storage and conversion systems. However, the adsorption of chloride ions (Cl − ) to active sites can degrade oxygen reduction reaction (ORR) activity stability, thus reducing catalytic performance. In this paper, a curved FeN 4 single atomic structure designed by utilizing curvature engineering, which turns harmful Cl into benefit on Fe site that changes rate determining step ORR reduces overall barrier according density functional theory (DFT) calculation.
