A monolithic porous carbon-based chainmail electrode (Co₂P@CSA) is fabricated via the direct carbonization of Co²⁺-cross-linked starch aerogel (Co²⁺-SA) followed by vapor phosphorization. Thanks to the high porosity, excellent electrolyte wettability, unique chainmail structure of carbon layer-protected Co₂P, and good mechanical strength, the monolithic chainmail Co₂P@CSA electrode demonstrates excellent activity and durability for alkaline HER, OER, and overall water splitting (OWS) at high current densities and a great potential being integrated into a solar-to-hydrogen conversion system with impressive performance.
