摘要

A novel BaCl₂-TiO₂-SnO₂ catalyst was prepared and studied for the oxidative dehydrogenation of ethane (ODE). Slight changes in textual properties and crystal structures of the catalyst were observed after ODE reaction. Nonetheless, both Ba^2 + and Cl^{鈭?/sup> ions were found to segregate on catalyst surface during the reaction. The vital and positive effects of Cl鈭?/sup> ions in the catalyst have been demonstrated by control experiments with catalyst free of Cl鈭?/sup> ions. The BaCl₂-TiO₂-SnO₂ catalyst show good activity and selectivity in ODE reaction, making it an alternative for ethylene synthesis using a low-cost feedstock such as ethane.}
