O1s的XPS峰一般会分成两个，表面氧和晶格氧，表面氧并不是所说的氧杂质，而是表面的羟基、水啊、氧空位啊什么的，具体的文献都有解释，MgSO4中的氧应该对应于晶格氧，而Mg (OH)2.2H2O应该对应于表面氧，至于三种氧峰 ... 感谢回复！ 您说的MgSO4对应晶格氧、H2O对应表面氧我能理解，但Mg (OH)2也是对应表面氧吗？ 我查了一些数据，金属氢氧化物大多在531eV处，这应该对应的是晶格氧吗？ 感谢回复！ 您说的MgSO4对应晶格氧、H2O对应表面 …

2023年7月3日 · X-ray photoelectron spectroscopy (XPS) is widely used to determine the chemical and electronic states of atoms within a material. However, it is often complex to interpret the O 1s region in metal oxides, where an ∼531 eV binding energy feature appears between lattice oxygen (∼530 eV) and oxygen-containing surface species (∼532 eV).

Gaussian XPS peak fitting was used to deconvolute the broad spectrum of O 1s at 531.8 eV, which produced two distinct peaks at 531.1 and 532.8 eV which are ascribed to the M − O and M − OH ...

These reference pages contain tips and techniques that are designed to help both the novice and advanced XPS user.

o1s羟基峰（O1s hydroxyl peak）是指在X射线光电子能谱（X-ray photoelectron spectroscopy，简称XPS）中观察到的氧原子的O1s能级的特定能量位置。 在这个位置上，氧原子与氢原子形成了化学键，通常被称为羟基（hydroxy

Many (pure) oxide samples exhibit a secondary structure to higher binding energy of the main lattice oxygen peak. Careful consideration of the sample history can aid in the identification of this peak. Commonly, this may be ascribed to surface hydroxyl (OH) groups or even defects in the metal oxide lattice.
