运用ＴＰＳＲ、ＴＲ－ＦＴＩＲ和化学捕获技术（ＣＨ３Ｉ作捕获剂），探讨了Ｒｈ／ＳｉＯ２催化剂上的ＰＯＭ反应机理，由此提出热分解氧化机理，认为ＣＨｘ（ｘ＝１～３）和ＣＨｘＯ（ｘ＝１～３）可能是反应物种。
The mechanism of POM reaction on Rh / SiO2 catalyst was discussed by using TPSR, TR-FTIR and chemical capture technique (CH3I) as capture agent. The mechanism of thermal decomposition and oxidation was proposed. It is considered that CHx (x = 1-3) and CHxO = 1 ~ 3) may be the reaction species.
