PLIAP检测化学反应中间生成物机理的探讨

A Study Of the Mechanism of Detecting Intermediates of Cheimcal Reactions by PL IAP

化学反应中间生成物的检测对反应基元步骤、历程和机理的研究有明显的重要性。运用ＰＬＩＡＰ，我们成功地实现了对一些化学反应中间生成物的检测￣［１－４］，搞活ＰＬＩＡＰ能检测化学反应中间生成物的机理对于明确这种检测方法的有效性和扩大其应用有重要意义。本文通过对于运用ＰＬＩＡＰ检测表面催化反应中间生成物的实验条件和结果的分析，初步探讨了用ＰＬＩＡＰ检测表面化学反应中间生成物机理。

t is important to detect the interniediates of chemieal reactions for the study of theirelementary stepe and mechaiusmis. We have successfully detected the interniediates of some anrfacechemieal reactions by using pulsed laser imaging atom probe. According to the experimentalconditions and result,the mechanism of detection of the intertnediates is explored.
