The modified extractant exhibits enhanced coordination selectivity toward yttrium, resulting in significantly improved separation factors in cascade extraction. Mechanistic studies reveal that oxygen vacancies and interfacial electronic structure cooperatively stabilize *OOH and govern its selective reactivity. This work establishes a general paradigm for coupling electrocatalysis with precision molecular editing, offering a new strategy to overcome long\u2010standing selectivity limitations in separation
