Abstract：Butenes and butadiene are important raw materials for manufacturing a large number of chemical products such as resins, rubbers. With the increasing demand of butenes and butadiene, oxidative dehydrogenation (ODH) of n-butane has been recognized as a promising process, which attracts widely attention at home and abroad. The activity of alkenes is higher, which easily occurs to total oxidation, leading to the lower selectivities of alkenes. Therefore, seeking high efficiency catalyst will be the critical factor for this reaction. More recently, hydrotalcite-like compounds as precursors for mixed oxides as catalysts for the ODH reactions have received a large number of attentions, due to their high surface areas, the controllability of its surface acidity/basicity. In this paper, a class of new efficient catalysts about catalyzing oxidative dehydrogenation of alkanes were summarized, and explored the reaction mechanism of catalysis.
