PURPOSE: To convert hazardous NOx into harmless nitrogen gas, NOx is first oxidized to NO by electric excitation, and then introduced into catalyst reduction chamber for the reduction of NO into harmless N2 gas. CONSTITUTION: Chemical formula of oxidative catalytic electrode employed in non-thermal plasma chamber is represented as follows, BT-MO-X where B denote bismuth, T denote titanium dioxide, MO denote metal oxides such as vanadium pentoxide, tungsten trioxide, molybdenum trioxide, manganese dioxide, copper oxide, cobalt oxide, and X denote silver iodide or potassium iodide. Chemical formula of reductive catalytic electrode employed in catalytic reduction chamber is represented as follows, TiSiC-M where Ti is titanium or titanium dioxide, Si is silicon, C is graphite, and M is metal such as nickel and silver.
