In this study, to remove environmental pollutants, we used iron oxide incorporated carbide nanofiber (IOC) composites as heterogeneous catalysts for enhanced decomposition performance and heavy metal absorbents. IOCs were synthesized via electrospinning, a promising technique reliably producing continuous ultrathin nanofibers. The water-vapor-activated IOC (Act-IOC) showed high crystallinity of Fe3O4 nanoparticles large surface area (405.2 m2/g). During the water vapor activation process, Fe3C in carbon oxidized, aggregated, grew from small particles. addition, meso-/macroporous structures formed improved area, increasing number available active sites catalytic reactivity. We confirmed that time 1 4 h degradation adsorption efficiencies by causing crystal growth area. These results indicate Act-IOC had highest photodegradation tetracycline ciprofloxacin. Moreover, better affinity positively charged ions (Pb) than other because their higher negative charge. Consequently, verified an appropriate is critical. imply composite highly efficient pollutant removal.
