Description
Technical Field
The invention belongs to the technical field of synthesis of molybdenum disulfide/titanium dioxide composite photocatalysts, and particularly relates to a preparation method and application of a metal phase molybdenum disulfide/titanium dioxide nanotube composite photocatalyst.
Background
In recent years, with the increasing severity of water body antibiotic pollution, clean and efficient pollution treatment schemes are increasingly emphasized. Among them, the photocatalytic technology is considered to be an effective way to solve the antibiotic pollution of water body due to the advantages of cleanness, no pollution, low cost and the like. Semiconductor photocatalysts are widely researched in the aspect of degrading organic pollutants, and the search for efficient photocatalysts is always the research focus in the field.
TiO2 is applied to the research of the photocatalysis field for a long time due to the excellent photoelectric property, titanium dioxide nanotubes (TNTs) are a one-dimensional titanium dioxide material, compared with zero-dimensional titanium dioxide nanoparticles, the structure has larger specific surface area, higher utilization rate of sunlight, stronger adsorption effect and larger potential in the photocatalysis field. However, the photocatalytic ability is limited by the characteristics of titanium dioxide such as large forbidden bandwidth, poor response to visible light, high recombination efficiency of photo-generated electrons and holes, and the like, so that a material needs to be introduced for modification. Research shows that the catalytic performance of the catalyst can be effectively improved by loading MoS2 on the surface of TiO 2. The metallic phase molybdenum disulfide (1T-MoS2) possesses higher electron transfer efficiency and more abundant active sites than the semiconducting phase molybdenum disulfide 2H-MoS2, however previous studies have used 2H-MoS2 as a co-catalyst due to 1T-MoS2 instability. The preparation method of the stable 1T-MoS2 is mature at present, but no 1T-MoS2 and TiO2 composite material photocatalyst is reported.
Accordingly, there is a need for improvements in the art.
