Hierarchical Pore Engineering in Al <sub>2</sub> O <sub>3</sub> /UiO‐66 Nanoarchitectures Synergistic Enhancement for Superior Phosphate Capture From Water
In this study, a hierarchical porous (HP) Al<sub>2</sub>O<sub>3</sub>/HP-UiO-66 composite was prepared via a facile template and solvothermal strategy. The material exhibits a high adsorption capacity for phosphate, with a maximum theoretical value of 303 mg/g based on the Langmuir model-eight times greater than that of the original UiO-66. It also displays excellent selectivity for phosphate over common ions in domestic wastewater, along with a wide pH stability range (2-10) and rapid adsorption equilibrium, reaching saturation within 90 min. Moreover, the composite maintains over 85% of its adsorption efficiency after six cycles. These results demonstrate that Al<sub>2</sub>O<sub>3</sub>/HP-UiO-66 possesses enhanced adsorption capacity, faster kinetics, improved acid-base resistance, and superior selectivity, highlighting its potential for effective phosphate removal from wastewater.
