The terms and definitions defined in GB/T 30544:1 and the following apply to this document: 3:1 photocatalysis nanomaterials Under the excitation of a certain light source, nanomaterials can produce photocatalytic effects: 3:2 photolysis performanceindex The ability of photocatalytic nanomaterials to degrade organic matter per unit time:

4 Principles

Using gas-solid reaction and photocatalytic reaction (see Appendix A), the samples loaded with photocatalytic nanomaterials were placed in a closed reactor with benzene evaporation air contact: Let the sample stand still to reach the equilibrium state of adsorption of benzene vapor; under the irradiation of ultraviolet light source, it is measured by gas chromatograph at regular intervals: Determine the concentration of benzene in the reactor, and use the least squares method to fit the linear slope of the test data according to the concentration change, which is the photocatalytic material to benzene: photolysis index:

5 Test equipment and reagents

5:1 Reactor system 5:1:1 Reactor The reactor includes two parts: a sealing cover and a sample pool (see Figure 1), and the sealing cover and the sample pool are sealed by a zipper lock: sealing cap (see ......
