考察了Ni V O系列催化剂对丙烷氧化脱氢反应的催化性能 ,结合XRD和电导法等表征结果研究了催化剂的物相结构与催化活性之间的关系 .结果表明 :同n型半导体氧化物相比 ,p型半导体具有优良的催化性能 ,并且丙烯的选择性与催化剂中NiO及Ni3V2 O8相的共存有关 .适当控制反应条件 ,42 5℃时该系列催化剂上可达到1 8 6%的丙烷转化率和 49 9%的丙烯选择性 . The catalytic performance of Ni VO catalysts for the oxidative dehydrogenation of propane was investigated, and the relationship between the phase structure and the catalytic activity of the catalyst was investigated by XRD, conductivity and other characterization results. The results show that compared with the n-type semiconductor oxide , the p-type semiconductor has excellent catalytic performance, and the selectivity of propylene is related to the coexistence of NiO and Ni3V2O8 phases in the catalyst.A proper control of the reaction conditions can achieve a conversion of propane of 186% on the series of catalysts at 42 5 ° C And 49 9% propylene selectivity.
