Selective oxidation of H2S to sulfur over CeO2-TiO2 catalyst
E-mail:
The catalytic oxidation of hydrogen sulfide (H2S) to elemental sulfur was studied over CeO2-TiO2 catalysts. The synthesized catalysts were characterized by various techniques such as X-ray diffraction, BET, X-ray photoelectron spectroscopy (XPS), temperature-programmed desorption of ammonia, and scanning electron microscopy (SEM). Catalytic performance studies of the CeO2-TiO2 catalysts showed that H2S was successfully converted to elemental sulfur without considerable emission of sulfur dioxide. CeO2-TiO2 catalysts with Ce/Ti=1/5 and 1/3 exhibited the highest H2S conversion, possibly due to the uniform dispersion of metal oxides, high surface area, and high amount of acid sites.
