2D Boehmite/Mesoporous Nanosphere Composites with Hierarchical Ion Transport for Efficient Capacitive Deionization

Abstract

Mesoporous nanospheres coated with 2D Boehmite nanosheets were synthesized. The hierarchical ion‐transport networks within this engineered structure facilitate efficient Na+ transport. The optimized composite exhibits a high salt adsorption capacity (131.3 mg g⁻¹, 1.2 V) and good regenerative stability (93.5%). Advances composite materials design for desalination technologies.
