When the pores of ceramics materials such as zeolite and mesoporous silica are utilized as the reaction field, the gaseous molecules which are originally known as the inert gases are activated. In this work, we established the preparation method of copper ion-exchanged zeolite having the irreversible adsorption property of dinitrogen gas at room temperature. Taking account of nitrogenase enzyme exhibiting the fixation of dinitrogen, we examined the state of dual copper site formed in zeolite pore by using ethane as a probe molecule. The result gave the important information for the understanding of the state of active center for the fixation of dinitrogen in the copper ion-exchanged zeolite.

当利用沸石和介孔二氧化硅等陶瓷材料的孔作为反应场时，原来被称为惰性气体的气体分子被激活。在本工作中，我们建立了常温下对氮气具有不可逆吸附性能的铜离子交换沸石的制备方法。考虑到固氮酶对氮素的固定作用，我们以乙烷为探针分子，考察了沸石孔内双铜中心的形成状态。这一结果为了解铜离子交换沸石中氮的固定活性中心的状态提供了重要信息。
