Abstract :
The degradation of acetaldehyde in the gas phase over Co-MCM-41, Ce-MCM-41 and MCM-41 under dark condition was studied by time-resolved microwave sensor (TRMS). Characteristic of the microwave cavity was simulated by commercial finite element software ANSYS, and the relation between reaction time and moisture content of the catalyst powder during the process of the acetaldehyde degradation was obtained. It showed that Co-MCM-41 is an efficient catalyst for acetaldehyde degradation under ambient, dark conditions. The experimental results of the TRMS were in good agreement with that of Fourier transform infrared spectroscopy (FTIR).
