Ci. Tec. VL - 4 IS - 4 SE - Research articles DO - 10.37636/recit.v44274286 UR - https://recit.uabc.mx/index.php/revista/article/view/133 SP - 274-286 AB - <p><em>Chrysanthemum- like rutile phase titanium oxide (TiO<sub>2</sub>) nanoflowers were synthesized on the surface of Raschig borosilicate rings (</em>BRRs<em>).</em><em> The hierarchical nanoarchitecture was investigated using several physicochemical techniques: scanning electron microscopy (SEM), energy dispersion spectroscopy (EDS), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (IR), diffuse reflectance spectroscopy (DRS), zeta potential (ζ). TiO<sub>2</sub>-BRR were used as a packed column in a photocatalytic reactor, and their catalytic activity in the degradation of a bacteriostatic antibiotic: tetracycline (C<sub>22</sub>H<sub>24</sub>N<sub>2</sub>O<sub>8</sub>) was evaluated. The photocatalyst removed 91% of the emerging contaminant achieving an energy efficiency of 68% with an optimized loading of 75 TiO<sub>2</sub>- BRR and a pH of 4 at 25 ° C; without significant variation in at least three photodegradation cycles. This information can be used to develop supported TiO<sub>2</sub> photocatalysts aimed at eliminating emerging contaminants, offering a viable alternative.</em></p> ER -
