AB  - In this study, MnWO₄ nanoparticles were successfully synthesized via a CTAB-assisted hydrothermal method and evaluated for their photocatalytic degradation performance against Methyl Red (MR) dye under UV-C irradiation. Structural and morphological characterizations were performed using XRD, FTIR, SEM, and UV-DRS techniques, confirming the formation of highly crystalline monoclinic MnWO₄ with defect-rich surfaces. The photocatalytic experiments were conducted under UV-C light (254 nm) with a catalyst dosage of 0.5 g/L, initial MR concentration of 20 mg/L, and solution pH of 6.5. The synthesized MnWO₄ exhibited excellent degradation efficiency, achieving 98% MR removal within 90 minutes, outperforming several conventional photocatalysts. This work addresses a critical gap in the literature by demonstrating the enhanced activity of CTAB-modified MnWO₄ under UV-C light, offering a promising route for azo dye remediation. The findings suggest that morphology control and surface defect engineering significantly influence photocatalytic performance, making MnWO₄ a viable candidate for environmental applications.
