Abstract
CNT/Ce3+ doped TiO2 powder was synthesized using a sol-gel method and characterized by X-ray Diffraction, UV–vis Diffuse Reflectance Spectroscopy, FTIR, EDX, Raman, Transmission Electron Microscopy (TEM), BET and PL. Direct sunlight illumination was used to check the photocatalytic activity of CNT/Ce3+ doped TiO2 for hydrogen production from sulphide wastewater. Sulphide wastewater collected from various industries viz., STP (Sewage Treatment Plant), Refinery (Amine solution) and Tannery (soak pit) were used to test the photocatalytic hydrogen recovery. The suitable industrial wastewater which generates maximum hydrogen was used to check the effect of various operating parameters viz., sulphide ion concentrations, sulphite ion concentrations and catalyst dosage. The maximum hydrogen recovery achieved was found to be 14,500 μmol/h.
