The catalytic decomposition of NO by cationic platinum oxide cluster Pt3O4+ was investigated by mass spectrometry and thermal desorption spectrometry. Upon reaction with two NO molecules, molecular oxygen desorbed from the cluster at room temperature to form Pt3O4N2+. Then, at temperatures above 400 K, desorption of N2 from Pt3O4N2+ was observed. These processes were confirmed by isotope-labeling experiments, and the energetics of O2 and N2 release were determined by density functional calculations. The combination of these elementary steps resulted in the catalytic decomposition of NO by Pt3O4+.

阳离子氧化铂簇Pt 3 O 4 +对NO的催化分解
通过质谱和热解吸光谱研究了阳离子氧化铂簇Pt 3 O 4 +对NO的催化分解。在与两个NO分子反应后，分子氧在室温下从团簇解吸形成Pt 3 O 4 N 2 +。然后，在高于400 K的温度下，观察到N 2从Pt 3 O 4 N 2 +解吸。通过同位素标记实验以及O 2和N 2的能量学证实了这些过程。释放通过密度泛函计算确定。这些基本步骤的结合导致NO被Pt 3 O 4 +催化分解。
