A synergistic coordination-reduction interface for electrochemical reductive extraction of uranium with low impurities from seawater.

ABSTRACT: Electrochemical extraction of uranium from seawater is a promising strategy for the sustainable supply of nuclear fuel, whereas the current progress suffers from the co-deposition of impurities. Herein, we construct a synergistic coordination-reduction interface in CMOS@NSF, achieving electrochemical extraction of black UO₂ product from seawater. The internal sulfur of CoMoOS tailors the electron distribution, resulting in the electron accumulation of terminal O sites for strong uranyl binding. Meanwhile, the interfacial connection of CoMoOS with Ni₃S₂ accelerates the electron transfer and promoted the reductive properties. Such synergistic coordination-reduction interface ensures the formation and preservation of tetravalent uranium, preventing the co-depo
