2results about How to "Enhance light absorption" patented technology

This invention belongs to the field of photo-evaporation desalination of water, specifically relating to a composite photoevaporator for photo-evaporation desalination and its preparation method. Carbon nanotubes, which possess excellent light absorption and water transport capabilities, are dispersed in biomass materials. Simultaneously, a layer of copper acetate is sprayed onto the surface of the biomass materials containing carbon nanotubes, forming copper particles after carbonization. The photoevaporator prepared by this invention combines metal, carbon nanotubes, and biomass materials, exhibiting contrasting hydrophilic and hydrophobic properties and strong salt resistance.

The application discloses a supported photocatalyst, a preparation method thereof and application of the photocatalyst in hydrogen sulfide decomposition. x MXene, wherein T x represents surface functional groups -O, -F, -OH) and a semiconductor material cadmium sulfide (CdS) loaded on the surface of the material, namely CdS / Mo2CT x photocatalyst; the photocatalyst directly decomposes hydrogen sulfide in a special quartz reactor filled with the supported photocatalyst to form a micro reaction bed, pure hydrogen sulfide (H2S) gas is introduced, and then the decomposition is carried out under irradiation of a laser; in the process, hydrogen sulfide is decomposed into hydrogen (H2) and sulfur (S). The application has the advantages of simple operation, mild conditions, high decomposition efficiency and the like, and can realize direct decomposition of hydrogen sulfide under the action of light only.
