甲酸酯(HCOO)是甲酸在Cu(100)和Cu(110)表面催化分解的稳定中间产物.利用近边X射线吸收精细结构(NEXAFS)研究HCOO在铜表面的吸附结构和电子态是众多研究者感兴趣的课题.Crapper测量了HCOO-Cu(110)的氧原子K-边NEXAFS谱(简称氧谱),氧谱的特点是存在π和σ两个明显的共振峰.Somers重复上述实验,并测量了碳
The formate (HCOO) is a stable intermediate for the catalytic decomposition of formic acid on Cu (100) and Cu (110) surfaces. The adsorption structure and electronic states of HCOO on copper surface are studied by using near-edge X-ray absorption fine structure (NEXAFS) Researchers interested topic.Crapper measured HCOO-Cu (110) oxygen atom K-side NEXAFS spectrum (oxygen spectrum), the oxygen spectrum is characterized by the existence of π and σ two obvious resonance peaks.Somers repeat the above experiment , And measured the carbon
