    Introduction:
         The gas phase catalytic system is to place a sample of the photocatalytic material in air containing contaminants to obtain its performance of purifying air under the action of light. Among them, formaldehyde, acetaldehyde and the like are used as reaction pollutants. During the test, the reaction gas passes through the reactor at one time. At this time, the sample in the reactor oxidizes and decomposes formaldehyde and acetaldehyde under the action of light, and the concentration of formaldehyde and acetaldehyde at the outlet of the reactor after illumination is obtained, and this value is compared with the outlet before illumination. The concentration comparison shows the photocatalytic degradation rate of formaldehyde and acetaldehyde. Increasing the concentration of the reactants, repeating the photocatalytic degradation of formaldehyde and acetaldehyde in the test sample, and comparing with the first test results, the stability of the photocatalytic performance is obtained. Finally, the air purification performance of photocatalytic materials samples was evaluated by photocatalytic degradation rate and stability of formaldehyde and acetaldehyde.
    The gas phase catalytic system is composed of a reaction system, a gas path system, a light source system, and an analysis system.
    The gas phase photocatalytic performance test of the sample can be carried out in a continuous flow reaction apparatus or in a closed reaction apparatus consisting of a reactor, a gas supply, a light source system, and a photocatalytic reactor. The reaction gas is prepared by mixing standard formaldehyde gas, acetaldehyde gas, oxygen gas, nitrogen gas, air, and the like. At a certain temperature, a known concentration of formaldehyde or acetaldehyde reaction gas can be continuously introduced into the reactor at a constant flow rate or intermittently introduced into the reactor. The flow rate of the reaction gas and the concentration of formaldehyde and acetaldehyde are respectively controlled by the gas mass flow meter.
