Abstract

The invention belongs to the technical field of nano composite materials, and discloses a preparation method and application of a 1D Sb2S3 nanorod/3D ZnIn2S4 composite structure. The method is as follows: firstly hydrothermally synthesizing 1D Sb2S3 nanorods, then dispersing the 1D Sb2S3 nanorods into deionized water to form a suspension, and finally, using in-situ hydrothermal method to prepare the 1D Sb2S3 nanorod/3D ZnIn2S4 composite structure. The composite structure prepared by the method can be applied to catalytically degrade 2-thiol benzothiazole under visible light or decompose waterto produce hydrogen under sunlight. The method has rich raw materials, simple operation process and mild reaction conditions, and belongs to a green synthesis method. The 1D Sb2S3 nanorods are combined with 3D ZnIn2S4 nanostructures to make full use of the in-situ growth characteristics, and close contact between the 1D Sb2S3 nanorods and the 3D ZnIn2S4 nanostructures is formed to achieve efficient transmission and separation of photogenerated electrons, improve the electron transport capability in the composite, and broaden the light absorption range of a single photocatalyst, so that the overall photocatalytic activity is enhanced, and the 1D Sb2S3 nanorod/3D ZnIn2S4 composite structure has important and broad application prospects in environmental management and energy conversion.

Description

technical field [0001] The present invention relates to a 1D Sb 2 S 3 Nanorod / 3D ZnIn 2 S 4 The invention relates to a method for preparing a composite structure, which belongs to the application in the field of preparation of nanocomposite materials and environmental protection. [0002] Background of the invention [0003] In recent years, with the development of industry, the problem of environmental pollution has become more and more serious, especially the deterioration of water environment. Due to the shortcomings of traditional treatment methods such as low removal efficiency, high cost, and secondary pollution, photocatalytic oxidation technology has begun to receive widespread attention, and the corresponding semiconductor materials have also become a hot spot in the field of materials. However, the excited state photogenerated electron-hole pairs in most monomeric semiconductor materials are very unstable and easy to recombine, resulting in low photocatalytic pe...
