中文摘要：

采用微波草酸盐共沉淀法制备了焦钒酸镍Ni2V207催化剂，并用XRD、BET、H2-TPR、XPS、TEM和电导等技术表征。研究了Ni2V20，催化剂的丙烷氧化脱氢（ODH）制丙烯催化性能与其表面物种的关系。TPR和XPS实验结果显示P型半导体焦钒酸镍Ni2V20，催化剂中，晶格氧可以较容易转换成未完全还原氧，使催化荆内各种价态的钒之间易于进行氧化还原反应并形成氧缺位，从而催化剂的表面含有较多未充分还原氧物种O-和V^4＋物种。从而使其具有较高的丙烯选择性。

英文摘要：

The pyro-Ni2 V2 O7 catalysts were prepared by oxalate co-precipitation method with microwave heating and characterized by X-ray diffraction （XRD）, BET, H2-TPR, XPS, TEM and conductivity measurement. The surface property of Ni2 V2 O7 was studied by XPS and the catalytic performance for the oxidative dehydrogenation of propane to propylene has also been investigated. The TPR and XPS results illustrated that the transformation of the lattice oxygen to non-complete reduction oxygen in Ni2 V2 O7 catalyst might, promote the oxidation-reduction reaction between different valence vanadium and promoted the oxygen vacancy formation, This then led to abundant non-complete reduction oxygen O^- and V^4＋ species formation over the surface of Ni2V2O7 catalyst. That high catalytic performance on p-type semiconductor Ni2V2O7 was related to the abundant oxygen species O^- and V^4＋ species existed over this catalysts.
