Co-Zeolitic Imidazolate Framework@Cellulose Aerogels from Sugarcane Bagasse for Activating Peroxymonosulfate to Degrade P-Nitrophenol

An efficient, green and reusable catalyst for organic pollutant wastewater treatment has been a subject of intense research in recent decades due to the limitation current technologies. Cellulose based aerogel composites are considered be an especially promising candidate next-generation catalytic material. This project was conducted order evaluate behavior ability sugarcane bagasse aerogels remove P-Nitrophesnol from waste-water aqueous. Co-Zeolitic imidazolate framework@ composite catalysts were successfully prepared via simple situ synthesis. The structure hybrid their efficient peroxymonosulfate (PMS) activation degradation p-nitrophenol (PNP) investigated. As result, aerogels/PMS system removed 98.5% PNP (10 mg/L) within 60~70 min, while traditional water technology could not achieve this. In addition, through free radical capture experiment electron paramagnetic resonance (EPR), mechanism Further found that can effectively activate PMS produce sulfate (SO4• −) hydroxyl (OH• ). Both them contributed PNP, SO4• − plays crucial role degradative process. most important feature easily separated solution. obtained results showed outer coating cellulose stabilize Co-ZIF reduce dissolution cobalt ions under complex reaction conditions. Moreover, exhibit excellent reusability environmentally friendly with efficiency. work provides new strategy applications material reusability.
