The present invention is a method of treating nitrogen oxides using an ozone and catalyst hybrid system, as well as an apparatus, specifically relating to a method of treating nitrogen oxide using an ozone and catalyst hybrid system comprising: 1) removing moisture from the nitrogen oxide polluted air to be treated; 2) contacting the moisture-removed nitrogen oxide polluted air with ozone to oxidize NO in said polluted air to NO2; 3) reacting the residual ozone with a catalyst to generate oxygen radicals and then, reacting the oxygen radicals with the nitrogen oxide polluted air from step 2) to oxidize NO2 in the polluted air to NO3−. The nitrogen oxide treatment method and apparatus according to the present invention can effectively treat harmful nitrogen oxides, such as NO, NO2, using an ozone and catalyst hybrid system at room temperature without requiring a high temperature reaction or an ammonia gas as a reducing agent. In addition, the method and apparatus according to the present invention can be useful in the removal of nitrogen oxides in various areas because they can prevent secondary air pollution resulting from the use of ozone.
