Abstract (EN): Growing concerns regarding the inefficient degradation of persistent pollutants, such as ibuprofen, in water necessitate the development of advanced treatment methods. Nb2O5, with its properties resembling those of TiO2, emerges as a promising alternative catalyst for advanced catalytic treatments. In this work, we demonstrate the exceptional catalytic ozonation and photocatalysis performance of Nb2O5/MWCNT nanocomposites synthesized via three sol-gel methods. These composites achieve complete ibuprofen degradation within 30 min, outperforming conventional catalysts and ozonation alone due to their enhanced surface area and synergistic interactions. Nb2O5/MWCNT presents a compelling solution, offering an efficient and sustainable approach to water purification.
