Ｌａ２－ｘＳｒｘＮｉＯ４上Ｏ２的ＴＰＤ研究表明，氧的脱附性能与催化剂结构中Ｎｉ２＋和Ｎｉ３＋的性质及含量有关，晶格氧直接参与了ＣＯ的氧化与甲烷的氧化偶联．
The TPD study of O2 on La2-xSrxNiO4 shows that the oxygen desorption performance is related to the properties and contents of Ni2 + and Ni3 + in the catalyst structure. The lattice oxygen is directly involved in the oxidation of CO and the oxidative coupling of methane.
