Wastewater treatment is a crucial global concern with substantial environmental and public health ramifications. The degradation of carcinogenic impurities from industrial and domestic effluents has become challenging with conventional methods. Titanium dioxide‑carbon dots (TiO2@CDs) nanocomposite was synthesized from bulk TiO2 employing Ananas comosus as carbon source via simple ultrasonication for photocatalytic degradation of pollutants. The present work highlights the tailored bandgap of TiO2@CDs specifically tuned to 2.31 eV, making it suitable for utilizing visible light radiation. The structural, electrochemical and optical characteristics of the synthesized TiO2@CDs nanocomposite were characterised using Ultraviolet-visible spectroscopy, X-ray photoelectron spectroscopy, Scanning electron microscopy, Fourier-transform infrared, and X-ray diffraction. Results showed that TiO2@CDs nanocomposite achieved 81% photocatalytic degradation of MB dye in 120 mins. Thus, this study opens a new possibility for developing effective semiconductor nanoparticles for applicability in photo-catalysis.
