ABSTRACT
In this work, we synthesised TiO2 nanomaterials using the hydrothermal method. Confirmation of the nanomaterials was performed with several analytical techniques, including UV-DRS, FTIR, XRD, Raman, and SEM-EDX. The UV-Vis spectrum showed an absorption peak at 425 nm, corresponding to a band gap of 2.91 eV. FTIR analysis identified functional groups such as 415 cm-1 (Ti-O-Ti) and 1200 cm-1 (-OH). SEM-EDX confirmed a quasi-spherical morphology and the presence of Ti and O elements. XRD analysis determined an average crystallite size of 120 nm. The photocatalytic activity of the synthesised TiO2 nanomaterials was assessed by degrading Erythrosin B (EB) dye under UV-visible light irradiation. The EB degradation rate reached 96.14% at 135 min, demonstrating excellent photocatalytic efficiency. The TiO2 nanomaterials enhance separation efficiency and suppress electron-hole pair recombination. Thus, this work highlights the significant potential of nanomaterials to develop effective photocatalysts for the degradation of organic pollutants.
