Background: The 1-Naphthol, one of the derivatives of naphthalene, is the most significant industrial chemical that is widely used in the production of dyes, pharmaceuticals, and biochemical processes.
Methods: In the present study, N, S-doped TiO2 thin film immobilized on silica sulfuric acid (SSA) glass microspheres (MS) was investigated as a novel high efficient photocatalyst. The N, S-doped TiO2 immobilized on SSA was fabricated using a simple modified sol–gel process. Its photocatalytic activities were then assessed using 1-naphthol solution in the presence of visible light. The physico-chemical properties of photocatalyst were characterized using energy-dispersive X-ray (EDX), scanning electron microscope (SEM) images and X-ray diffraction (XRD) pattern.
Results: According to the obtained results, the optimal pH, time, concentration, and removal efficiency of 1-naphthol for N, S-doped TiO2 /SSA was 5, 50 minutes, 25 mg/L and 92.12%.
Conclusion: The present study confirms the usability of the immobilized N, S-doped TiO2 on SSA glass MS as a novel, effective, and efficient technique for treatment of wastewater containing 1-naphthol under visible light.
