为了考察添加剂对β-（VO）2 P2 C7催化剂活性中心的影响，采用BET、XRD和NARP（NO-NH3矩形脉冲）技术对以VOHPO 4. 0. 5 H2O为载体的VPO催化剂进行了表征，并以正丁烷选择氧化为反应对象考察了催化剂的连续流动反应性能。讨论了催化剂的结构和表面活性位V=O物种的数量与助剂和制备过程的关系，并讨论了催化剂的结构因素和活性位对催化性能的影响。
In order to investigate the effects of additives on the active sites of β-(VO)2P2C7catalyst, a series of promoted VPO catalysts, prepared by the impregnation of VOHPO4.0.5H2O with solutions containing promoter elements, were characterized with BET, XRD, and NARP (NO-NH3Rectangular Pulse) technique, and their catalytic properties were examined with the continuous flow reaction of the selective oxidation of n-butane. The structure of catalyst and the number of surface V=O species as the active sites are discussed in relation to the promoter and the preparation procedure, and the catalytic property is discussed in relation to the structural factors and the active sites.
