摘要: 论述了挥发性有机污染物(VOCs)催化反应过程机理研究的现状,包括催化剂的表征、催化过程研究方法以及不同的研究体系。催化剂表征使用原位技术以及X射线吸收精细结构(XAFS)方法可以更好地阐述催化剂在催化过程中的作用与机制。催化过程研究主要包括催化反应动力学模拟(Power-rate Law、Mars-van Krevelen Model、Langmuir-Hinshelwood),反应产物监测(原位红外技术、原位核磁技术、暂态技术、同位素示踪技术),量子化学计算等。其中,反应动力学是使用较为广泛的研究催化反应机制的技术之一。反应产物监测可以得到直观的认识,获得了广大学者的关注。量子化学计算只作为论证。

Abstract: Reviews the research status of volatile organic compounds catalytic oxidation process and mechanism,such as catalyst characterization,research methods of catalytic process,and different research systems. In-situ technology and X-ray absorption fine structure (XAFS) in catalyst characterization can preferably elucidate the catalytic process and mechanism. The research of catalytic oxidation process mainly include reaction kinetic models (the Power-rate Law, the Mars-van Krevelen Model, and the Langmuir-Hinshelwood), reaction monitoring technology (In-situ FTIR, In-situ NMR, transient technique, isotopic tracing) , quantum chemical calculation, et al. Generally, reaction kinetics is one of the most widely techniques for the mechanism research of catalytic oxidation. The reaction products can be directly detected,which adsorb more attention. The research of quantum chemical calculation is just used for proof.
