[求助] XPS有两个峰不认识啊已有1人参与

这是做的Ni2P的催化剂。
xps以前没有接触过,一点不懂。希望各位师兄师姐给小师妹一点点帮助

852.9eV应该是Ni2P中Niδ+。857.1eV处峰应该是表面氧化的NIO...这些都是文献上看得。。。如果不对也请大神帮忙指出。。。

但是现在老师让我把下面剩下两个峰也分析一下。。。看见文献有描述。。但是不太理解,求指教。。。
文献原文:
Ni 2p core level spectrum involves two contributions (Fig. 3A). The first one, is assigned to Niδ+ in Ni2P phase and centered at 852.6 eV [44], and a second one is at
856.4 eV, corresponding to Ni2+ ions interacting possibly with phosphate ions as a consequence of a superficial passivation, along with the broad shake-up peak at approximately 6.0 eV above the Ni2+ species [45]. This satellite is due to divalent species [45,46], although in the literature has also been assigned to trivalent and oxysulfided nickel species


谢谢谢谢
