Preparation Of MnFe₂O₄/nanocarbon Composites And Their Photodegradation Properties For Tetracyclin

The issue of water pollution caused by the misuse of tetracycline(TC)has emerged as a pressing social concern.TC contains numerous toxic substances and possesses antibacterial properties that are resistant to adsorption and biodegradation,posing a serious threat to human health.Therefore,it is imperative to explore an economical and feasible approach for the efficient and rapid removal of TC from water.MnFe2O4 exhibits excellent ferromagnetism,chemical stability,UV-visible light absorption range,and minimal ion leaching,making it highly promising for applications in photocatalytic advanced oxidation technology(AOP).However,its use is hindered by problems such as agglomeration,weak adsorption capacity,and facile recombination of photogenerated carriers.To address these challenges,this study was conducted by following research:Fullerene soot(FC),single-walled carbon nanotubes(SWNTs),and boron-doped graphene aerogel(BGA)were combined with MnFe2O4 to synthesize MnFe2O4/FC,MnFe2O4/SWNTs,and MnFe2O4/BGA composites via solvent-thermal method.These composites were applied as photocatalysts to activate PMS for TC degradation.Compared to pure MnFe2O4,the incorporation of carbon nanocomposite agents resulted in faster photogenerated carrier transfer and separation,wider visible light absorption range,and reduced agglomeration.
