Abstract The release of Rose Bengal (RB) dye poses a significant threat to aquatic ecosystems, necessitating sustainable water treatment solutions. This study introduces novel photocatalytic approach utilizing titania nanotubes (TNTs) doped with varying contents gallium oxide (Ga₂O₃, 0–5%) via hydrothermal method. Characterization techniques, including FTIR, XRD, TEM, SEM, EDX, and XPS, confirmed the formation nanotubular structures enhanced surface area defect states. total organic carbon (TOC) measurement indicated effective mineralization RB dye. Among synthesized photocatalysts, 1% Gallium-doped (Ga-doped TNTs) achieved optimal degradation, decomposing 97% within 110 min under UV illumination, owing improved charge separation synergistic effects between Ga TNTs. Furthermore, Ga-doped TNTs demonstrated superior efficacy in mosquito control, 100% larvicidal mortality observed at 400 °C compared only 57.2% for Similarly, pupicidal rate 72 h increased from 26.2% 60.8% TNTs-400). findings emphasize dual functionality as efficient photocatalysts purification eco-friendly biopesticides, presenting promising strategy environmental remediation vector control.
