| الملخص: | <p dir="ltr">Dyes are among the most toxic and persistent pollutants in water, making it unsafe for human consumption and posing serious environmental threats. To tackle this challenge, we developed a sustainable approach by modifying TiO<sub>2</sub> with barium (Ba), creating a highly efficient photocatalytic material for the purification of dye-contaminated water. TiO<sub>2</sub> is considered a sustainable material due to its non-hazardous nature and chemical stability, making it an excellent candidate for dye degradation in water systems. However, it suffers from a low surface area and rapid recombination of photogenerated electron–hole pairs, which limit its photocatalytic efficiency. To overcome these limitations, we investigated a novel modification of TiO<sub>2</sub> nanotubes by doping them with Ba using the hydrothermal method. The resulting Ba-doped TiO<sub>2</sub> nanocomposite exhibited significantly enhanced photocatalytic activity for dye degradation. The material was characterized using Fourier-transform infrared spectroscopy, transmission electron microscopy, scanning electron microscopy, X-ray diffraction, and UV–Vis spectrophotometry. The results demonstrated a substantial improvement in photodegradation capability after doping TiO<sub>2</sub> with Ba. For Indigo Carmine dye, unmodified TiO<sub>2</sub> showed minimal degradation (no more than 4%), while Ba-TiO<sub>2</sub> achieved ~ 99% degradation. In the case of Azocarmine-G dye, TiO<sub>2</sub> degraded about 20%, whereas Ba-TiO<sub>2</sub> achieved ~ 81% degradation. For Benzopurpurin dye, TiO<sub>2</sub> and Ba-TiO<sub>2</sub> exhibited degradation rates of 43% and 97%, respectively.</p><h2 dir="ltr">Other Information</h2><p dir="ltr">Published in: Journal of Materials Science: Materials in Electronics<br>License: <a href="https://creativecommons.org/licenses/by/4.0" target="_blank">https://creativecommons.org/licenses/by/4.0</a><br>See article on publisher's website: <a href="https://dx.doi.org/10.1007/s10854-025-16219-3" target="_blank">https://dx.doi.org/10.1007/s10854-025-16219-3</a></p> |
