Problems solved by technology

But TiO 2 The forbidden band width (3.2eV) is wide, the spectral response range is narrow, and the absorption wavelength is mainly concentrated in the ultraviolet region (<387nm)
In the solar energy that reaches the ground, the energy in this band is less than 5%, while the proportion of visible light accounts for about 45% of solar energy, and the utilization efficiency of solar energy is low.

Abstract

The invention belongs to the technical field of function materials and relates to a preparation method of a copper-titanium-oxide mesomorphism material. The preparation method comprises the following steps of: uniformly dissolving soluble metallic copper slat and titanium salt in a mixed solution of alcohol / water according to a certain proportion, and adding a certain quantity of surfactant in the mixing process; performing hydrothermal reaction, filtering, washing, drying in the mixed solution of alcohol / water continually; and then performing thermal treatment in a muffle furnace to obtain the copper-titanium-oxide mesomorphism material. According to the preparation method, the technology is simple and convenient, the purity of the prepared material is high, the content of impurities is low, the preparation cost of the material is low, the performance of the material is excellent, and thus the material can be subjected to industrialized mass production. The copper-titanium-oxide mesomorphism material prepared by the method can serve as a photochemical catalyst responsive to visible light, and has wide application prospect in the fields of degradation of dyeing waste water and indoor harmful gas, photochemical catalysis disinfection and the like.

Description

technical field [0001] The invention belongs to the technical field of preparation of functional materials, and in particular relates to a preparation method of a copper-titanium oxide mesocrystalline material. Background technique [0002] Functional materials are a large class of materials with special electrical, magnetic, optical, acoustic, thermal, chemical and biological properties, and are important basic materials for high-tech fields such as information technology, biotechnology, energy technology and national defense construction. In recent years, the rapid development of mesocrystals has drawn more attention from chemists and physicists. Especially for materials chemists, mesogens offer new opportunities for materials design due to their microstructure (see H, Antonietti M. Mesocrystals and nonclassical crystallization, John Wiley & Sons, New York 2008.; Song R, H. Mesocrystals-ordered nanoparticle superstructures. Adv. Mater., 2010, 22, 1301-1330.). Mesogens...
