Seawater electrolysis is a potentially cost-effective approach to green hydrogen production, but it currently faces substantial challenges for its high energy consumption and the interference of chlorine evolution reaction (ClER). Replacing energy-demanding oxygen with methanol oxidation (MOR) represents promising alternative, as MOR occurs at significantly low anodic potential, which cannot only reduce voltage needed also completely circumvents ClER. To this end, developing high-performance...
