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.

Key words: volatile organic compounds（VOCs）, catalytic oxidation, reaction process and mechanism, research status
