“…[4][5][6][7] It has been listed as toxic chemicals by USEPA due to its severe toxicity and high environmental stability. [4][5][6][7][8][9][10] During past decades, a variety of porous materials have been developed for 4-NP adsorption from wastewater, such as graphene oxide-montmorillonite nanocomposite, [11] porous organic polymers, [12,13] porous carbon, [5] and metal organic frameworks. [14,15] However, the performance and reusability of these documented adsorbents DOI: 10.1002/marc.202200786 is far from practical applications, therefore, the preparation of high-performance adsorbents still keeps challenging.…”
