材料中的缺陷会改变键合能量，这可以从移位的峰或新出现的峰中观察到。因此，XPS可以作为一种有效的方法来检测材料中的氧空位与缺陷位点。经查阅文献可知，通过低频超声波制备含有氧空位的BiOI，并发现富含缺陷的BiOI（R-BiOI）纳米片表现出优异的光催化性能。富有缺陷的BiOI的O 1s XPS光谱证实了氧空位的存在，如图5...
首先,8.47% CABB@M-Ti和8.12% CBB@M-Ti的XPS全谱图证明了Br、Bi、Cs、O和Ti元素的存在。M-Ti,8.47% CABB@M-Ti和8.12% CBB@M-Ti的Ti 2p光谱显示出Ti4+离子具有对称的Ti 2p双峰。M-Ti的O 1s光谱中可以观察到晶格氧(530.2 eV)和表面羟基(532.3...
