Abstract

The removal efficiency of formaldehyde, the ozone generation and also the conversion rate of formaldehyde to carbon dioxide in the corona discharge system was investigated. This system was composed of a needle discharge electrode and a conductive manganese oxide catalyst honeycomb. There was an optimal needle configuration for the maximum formaldehyde removal and the least ozone generation. Moreover, the conversion rate of the formaldehyde to the carbon dioxide at the optimal needle configuration increased gradually with the discharge power
