英文摘要	Rational design of advanced adsorbed materials with hierarchically porous architecture, high surface area, and macroscopic shapeability is of great significance for boosting their potential in practical applications. Herein, a monolithic iron metal-organic gel/bacterial cellulose (denoted as Fe-MOG/BC) composite has been successfully fabricated based on an ultrafast, scalable, aqueous-based synthetic strategy at room temperature. As expected, the resulting Fe-MOG/BC aerogel possesses a three-dimensional (3D) hierarchically porous microstructure and abundant active sites, being ultralight, water-fast, and mechanically robust. Benefiting from these unique structural characteristics, the resulting Fe-MOG/BC composite exhibits superb saturated sorption capacity (495 mg g(-1)) toward arsenate, outperforming other reported nanoadsorbents. Further, the Fe-MOG/BC aerogel enables efficient decontamination of 5 ppm of As(V) to below the permitted threshold in drinking water (10 ppb) within 30 min, accompanied by excellent selectivity and reusability. Significantly, as an efficient filter unit, the Fe-MOG/BC aerogel (0.1 g) can continuously treat 3900 mL wastewater (spiked with 1 ppm As(V)) to the safe level. Such an excellent As(V) decontamination capability of Fe-MOG/BC together with the ease, low cost, and scalable production prefigures its huge prospects for practical wastewater remediation.
