Abstract

Abstract:

The effect of a Ce promoter on the catalytic properties of V/SiO₂ was investigated for the oxidative dehydrogenation of ethylbenzene (EB) to styrene (ST) with CO₂ (CO₂-ODEB). The catalysts were characterized by nitrogen adsorption, X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), H₂ temperature-programmed reduction (H₂-TPR), CO₂ temperature-programmed desorption (CO₂-TPD), and thermogravimetric analyses (TGA). It was found that incorporation of Ce into V/SiO₂ increased the dispersion of active V species, enhanced the redox properties of the system, and inhibited deep V reduction of V⁵⁺ to V³⁺ . The Ce promoter also improves the basicity of V/SiO₂ and CO₂ adsorption on the catalyst, and suppresses coke formation. The addition of a Ce promoter greatly improves the catalytic activity and stability of V/SiO₂ towards CO₂-ODEB. The ST yield and selectivity reach 55.6% and 98.5%, respectively, for CO₂-ODEB over the most efficient catalyst, V(0.8)Ce(0.25)/SiO₂, at 550℃, and a CO₂/EB molar ratio of 20. Moreover, after reaction for 12 h, the V(0.8)Ce(0.25)/SiO₂ still shows stable catalytic activity. The ST yield in CO₂ is higher than that in an inert N₂ atmosphere, showing the significant promoting effect of CO₂ on EB dehydrogenation; this is because CO₂ is a soft oxidant and can effectively keep/regain the high valence of V for high activity with CO₂-ODEB.
