Piezocatalysis offers a promising alternative, but its efficacy in single\u2010phase materials is restricted by the piezoelectric screening effect. Herein, we construct a zinc oxide@zinc selenide (ZnO@ZnSe) heterojunction as a high\u2010performance piezocatalyst for ultrasound\u2010stimulated uranium recovery. A spontaneous interfacial built\u2010in electric field with a ZnO\u2010to\u2010ZnSe orientation is established at the heterojunction, which actively mitigates the potential screening effect and amplifies the piezoelectric polarization. Consequently, the optimized ZnO@ZnSe\u201010 delivers an excellent uranium uptake capacity of 1372.7 mg\u00b7g\n                    <jats:sup>\u22121<\/jats:sup>\n                    , high extraction selectivity, and good cycling stability.
