3 Terms and definitions

The following terms and definitions apply to this document: 3:1 Photocatalytic materials and products Materials containing or using photocatalysts and having photocatalytic properties and various application products made of photocatalytic materials: 3:2 Zero-calibrationgas High-purity air with pollutant content less than 0:01mL/m3:

4 Principle of the method

The sample made of photocatalytic material is placed in a flow photocatalytic reactor, and air containing nitric oxide (NO) pollutants is passed through: After light irradiation, the reaction occurs, and the NO adsorbed on the surface is partially oxidized into nitrate, and part is converted into nitrogen dioxide (NO2), and the net is removed The amount of addition characterizes the air purification ability of the sample: Among them, NO and NO2 are tested by chemiluminescence method, nitrate ion is eluted with pure water, Sub-chromatographic determination: Note: The net removal of nitrogen oxides (NOx) is calculated by subtracting the NO2 production from the NO removal: ......
