Summary: Seawater electrolysis is challenging due to competitive kinetics between oxygen and chlorine evolution reactions. This study proposes an energy efficient strategy by coupling seawater splitting with urea decomposition to avoid hypochlorite formation. The design of Se/NiSe2 Mott-Schottky heterojunction is highly effective in this regard. Se/NiSe2 exhibits excellent energy saving and operational durability for alkaline seawater splitting with urea. The unique properties of Se and the reactive edges on Ni foam contribute to enhanced electrocatalytic activities, providing a promising approach for alkaline-urea-seawater electrolysis.
