Abstract: An oxidizing gas detection method and an apparatus thereof are provided for trace oxidizing gas detection. The detection method includes the following steps. First, perform an electroreduction reaction and a photoreduction reaction simultaneously to a metal oxide in which nanoconductors are distributed. Next, stop the electroreduction reaction and the photoreduction reaction, and read a resistance of the reduced metal oxide by applying a first pulse-width modulation signal. Next, provide an oxidizing gas to the reduced metal oxide, and photo-catalyze a redox reaction between the oxidizing gas and the reduced metal oxide. Next, read a resistance of the oxidized metal oxide by applying a second pulse-width modulation signal. Next, converse a concentration of the oxidizing gas according to a ratio of the resistance of the oxidized metal oxide and the resistance of the reduced metal oxide.
