本文用IR,TEM,FABMS,ESCA,XRD以及还原度的测定等方法,描述了Co/AlPO_4-5上Co_3O_4在氢作用下变成Co°,CoO以及未还原的Co_3O_4三种状态的还原过程和钴的颗粒分布的变化,并表明在还原过程中,可能有钴的簇状物生成,导致B酸形成。
In this paper, the reduction process of Co_3O_4 on Co / AlPO_4-5 into Co °, CoO and unreduced Co_3O_4 under the action of hydrogen is described by means of IR, TEM, FABMS, ESCA, XRD and the determination of reduction degree. Changes in the distribution of cobalt particles indicate that during the reduction process, there may be clusters of cobalt that lead to the formation of B acid.
