Purification module and refrigeration appliance

Abstract

This application relates to a purification module and a refrigeration device. The purification module includes: a conductive adsorption substrate configured as a porous structure with multiple pores distributed on the substrate; and multiple semiconductor nanoparticles, including light-emitting semiconductor structures and photocatalytic semiconductor structures. The multiple semiconductor nanoparticles are attached to the surface of the pores, and / or, multiple semiconductor nanoparticles are attached between the pores and the conductive adsorption substrate. In this purification module, the photocatalytic semiconductor structure on the semiconductor nanoparticles directly absorbs the light energy of the light-emitting semiconductor structure, improving the efficiency of converting electrical energy into electronic energy. Furthermore, it eliminates the need for an additional light emitter and the need to consider the positional design of the light emitter and photocatalytic material. Instead, it directly integrates the active sites for pollutant reactions onto the pores of the conductive adsorption substrate, shortening the distance between the pollutants and the active sites, reducing the diffusion time and path of pollutant molecules, and efficiently removing pollutants.
