A novel BaCl2-TiO2-SnO2 catalyst for the oxidative dehydrogenation of ethane

► A novel BaCl2-TiO2-SnO2 catalyst was prepared by grinding method for ODE reaction. ► Slight changes in textual properties and crystal structures were observed. ► The chloride ions in the catalyst play vital and positive roles. ► The catalyst shows good activity and selectivity in ODE reaction.
