With the growing demand for clean energy, efficient uranium extraction technologies are needed, especially from seawater, where uranium reserves are huge. Here, we developed a composite membrane by inserting Escherichia coli engineered with super uranyl-binding protein (SUP) within a two-dimensional (2D) MXene (Ti 3 C 2 T x ) layer. SUP endowed the bioinorganic hybrid membrane with ultrahigh selectivity for uranyl ions, while the engineered E. coli improved the mechanical strength and economy of the membranes. Experimental results showed that the membranes achieved precise recognition of uranyl ions and excellent ion screening performance (SF U/V ≈ 43, SF Na/U ≈ 158). Excellent separation performance and cyclic stability tests demonstrated the industrial application potential of the membrane. This method offers a green and sustainable solution, combining biological engineering and nanomaterial innovation, providing an environmentally friendly and efficient approach for uranium extraction from seawater, marking a significant advancement in the field of clean energy resource development.
