Abstract

In order to improve the performance of the plasma discharge catalytic air purifier (PDCAP), and to achieve the development of PDCAP, we studied the efficiency of nano-TiO2 catalyzing and decomposing formaldehyde as a catalyst in the PDCAP. In the experiment, we changed one parameter while fixed other parameters, and finally obtained a relationship between the efficiency of nano-TiO2 catalyzing and decomposing formaldehyde and every parameters. The result shows that, with the catalysis of plasma discharge, nano-TiO2 decomposes formaldehyde effectively; in the premise of other certain parameters, the efficiency of nano-TiO2 catalyzing and decomposing formaldehyde increases with the decrease of wind velocity, and reaches its peak value when the humidity is about 40%; the efficiency increases with the increase of the voltage between the two electrodes and exists polarity effect. The conclusions can provide a reference for the development of the PDCAP.
