Sulfate radical (SO4•−)-based advanced oxidation processes (SR-AOPs) has utilized metal-organic frameworks (MOFs) as efficient catalysts to generate sulfate radicals through peroxymonosulfate (PMS) activation in water treatment. The selection of a high-performance catalyst is not only crucial for effective water purification, but the recovery and separation of catalysts are also necessary for the practical application. In this study, a nanoarchitectured aerogel (Z67@AG) was fabricated by employing a shape-controllable, cost-effective and good adhesive agarose (AG) and Co-MOF. This approach makes it suitable for reusability, and can be applied in diverse filtration systems for industrial application. This aerogel demonstrated remarkable catalytic decomposition performance, achieving efficiencies of 95% and 88% within 8 and 10 min for dye and levofloxacin, respectively. It is anticipated that the suggested aerogel lead to simple synthesis of nanocomposites and novel applications.
