Abstract
The ongoing approach to overcome the environmental issues have pushed the research to search for sustainable, cost-effective, and valuable materials for dyes degradation. In 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 Infrared Spectroscopy (FTIR), X-ray diffraction (XRD), Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray spectroscopy (EDX) and UV-vis spectroscopy to evaluate the physical and chemical 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 (0.1g dose of catalyst, 20 ppm dye conc, pH acidic media, 150 minutes 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.
