The ongoing approach to overcome the environmental issues have pushed the research to search for sustainable, cost-effective, and valuable materials for dyes degradationIn this study, AC, (activated carbon) TiO2, (Titanium dioxides) and AC/TiO2 nanocomposites were fabricated by Sol-gel method and further passed through these characterization techniques such as Fourier Transform IR Spectroscopy (FTIR), X-ray diffraction (XRD), SEM (SEM) and Energy Dispersive X-ray spectroscopy (EDX) and UV-vis spectroscopy to evaluate the phys. and chem. characteristics.Photocatalytic activity was assessed under UV-vis light irradiation, showed pseudo-first-order kinetics of Rhodamine B (Rh B) which showed 85 % removal efficiency from contaminated water under the standard reaction conditions.Various parameters like dose of photocatalyst, (0.1-0.5 g), dye concentrations (10, 20, 30 ppm), pH (acidic, neutral, basic), H2O2 conc (1-4 drops).AC/TiO2 material was found to be highly suitable which showed the better catalytic activity under the optimized reaction conditions (0.1 g dose of catalyst, 20 ppm dye conc, pH acidic media, 150 min light irradiation, 2 drops H2O2), enhanced selectivity for degradation of Rh B of 85 %, and greater catalytic stability under 5 cycles of regenerations with well preserved structure of composite.
