摘要	Mesoporous phosphate materials with chemical diversity and a high surface area are essential for their practical applications as heavy metal ion adsorbent materials. Herein, novel gallium aluminum phosphate mesoporous glasses are prepared through a simple aqueous sol-gel route free of any surfactant or template. The glass structure and its evolution from the gel to the final glass were monitored using solid-state NMR techniques, providing detailed insight into the reaction mechanism. During the formation of the mesoporous GaAlPO4 glass, the gallium entered into the PO4 tetrahedron via Ga-O-P bonds. The resulting mesoporous glass samples were tested as adsorbents to remove Pb(II) anions from solution and the ternary oxide glasses show high adsorption capacities (>36.63 mg g(-1), that is 0.18 mmol g(-1)). Owing to their integrated features (including their variable compositions, high specific surface area, tunable pore size and shape flexibility) as well as specific acid-base surface properties, such mesoporous gallium aluminum phosphate materials are also expected to have potential either as catalysts or catalyst supports for industrial applications.
