【摘要】 本文利用TPR、TPR-GC和XRD技术详细地研究了镍酸镧（LaNiO₃）的还原机理.同时还利用TPO和TPR考察了还原后样品的氧化还原可逆性.结果说明:LaNiO₃分两步还原,其中单电子还原过程伴随着三电子还原过程的同时进行.LaNiO₃还原中间产物为单斜晶点的LaNiO₃;此外,还原后的具有良好的氧化还原可逆性.更多还原

【Abstract】 this paper reported that the ledncing mechanism of Lathanum Nickelate （LaNiO₃）was studied detailly with TPR. TPR-GC and XRD technigues. Meanwhile, the oxidation-re-duction leversibility of the reduced sample has been mvestigated by TPO and TPR The resultsshowed that the reduction for LaNiO₃was divided into two steps, among of them, the single elec-tron reduction accompanied with three electrons reduction, the reducing medium product wasmenoclihic La₂Ni₂O₅; otherwise, the reduced priducts of LaNiO₃have well the oxidation-reduc-tion leversibility.更多还原
