| 摘 要： | The La-Ni complex oxide catalyst was prepared by solid state reactions under microwave. The structure and reducibility of the catalyst were characterized by using TG-DTA, XRD, TEM and TPR methods. At the same time the catalytic activity of oxidative dehydrogenation of ethylbenzene to styrene with carbon dioxide over the complex oxide nanoparticle was investigated.The Results show that the product is K2NiF4 nanoparticles,and the size is 13nm.The complex oxide sample had high activity for the oxidative dehydrogenation of ethylbenzene to styrene.
