Photocatalytic performance testing device under monochromatic light irradiation

Abstract

The invention relates to a photocatalytic performance testing device under monochromatic light irradiation, and the device comprises a base, a photocatalytic reaction area, an adjustable lamp post andLED monochromatic light sources. The adjustable lamp post is fixedly mounted at one side of the base; the photocatalytic reaction area is fixedly connected to the middle of the base, and the adjustable lamp post is composed of an adjusting lamp post main body, locking nuts and a telescopic rod at the upper part; the telescopic rod is arranged in the adjusting lamp post main body, and the telescopic rod can rotate; the locking nuts are symmetrically arranged at the two sides of the adjusting lamp post body and used for locking the telescopic rod; the top of the telescopic rod is connected withsix LED monochromatic light sources through hinges, and the six LED monochromatic light sources are evenly distributed and can be rotationally folded through the hinges. Scales are arranged on the surface of the telescopic rod. A photocatalyst of which the performance needs to be evaluated is placed in the photocatalytic reaction area, the length of the telescopic rod is adjusted to determine theillumination intensity under different distances, and the telescopic rod is rotated to determine the photocatalytic performance under different monochromatic light sources.

Description

technical field [0001] The invention relates to a photocatalytic performance testing device assisted by chemical experiments, in particular to a photocatalytic performance testing device under monochromatic light irradiation. Background technique [0002] Photocatalytic experiments are relatively common experiments in chemical experiments, and the photocatalytic performance of materials is mainly verified by comparative experiments. First of all, the position of the light source and the photocatalytic reaction area will affect the accuracy of the test results. The original photocatalysts can only be excited under ultraviolet light, and more and more photocatalysts that can be excited under visible light have been studied. Since there is only one condition of visible light in the experiment, the specific wavelength or specific color of light that excites the photocatalyst cannot be determined, which reduces the accuracy of the photocatalytic performance test. Illumination d...

Problems solved by technology

Since there is only one condition of visible light in the experiment, the specific wavelength or specific color of light that excites the photocatalyst cannot be determined, which reduces the accuracy of the photocatalytic performance test.

Illumination distance is one of the conditions that affect the intensity of light. Since the distance from the light source to the surface of the photocatalyst in the experiment may be different, it will affect the authenticity of the experimental results.
