Description
Technical Field
The invention belongs to the technical field of preparation of photocatalytic semiconductor materials, and particularly relates to a method for preparing BiOCl with adjustable thickness at room temperature.
Background
The increase of microbial resistance and antibiotic resistance caused by antibiotics contained in natural water has attracted great attention. Many antibiotics detected in aquatic environments, even at varying concentrations, can cause antibiotic resistance and have adverse effects on aquatic wildlife, ecosystem, and human health. The tetracycline belongs to tetracycline antibiotics, which are named because of common hydrogenated tetra-benzene rings in molecular structures, belong to broad-spectrum antibiotics and have inhibitory effects on gram-positive bacteria, gram-negative bacteria, spirochetes, rickettsiae, chlamydia, mycoplasma, protozoa and the like. The tetracycline is the antibiotic with the largest production amount and clinical use amount in the livestock and poultry raising industry, is continuously discharged into a water body and continuously exists in the water, becomes a new pollutant, and has potential harm to the environmental residue.
Photocatalysis has been widely used in water treatment in recent years due to its TiO content2The transition metal oxide semiconductor is the most studied transition metal oxide semiconductor, has good stability and good photocatalytic performance, but has a forbidden band width of 3.2eV, can only respond to ultraviolet light, and has low solar energy utilization rate. As another example, CdS is one of the most commonly used sulfides, and although capable of responding to visible light, has been very limited in its application due to its unstable and photo-corrosive properties. Therefore, the development of efficient, stable and practically applicable visible light-responsive semiconductor photocatalysts is a hot issue in the field of photocatalytic research.
In recent years, BiOCl as a novel semiconductor material has a good application prospect in the field of photocatalysis due to the characteristics of a special two-dimensional lamellar structure, easy regulation and control of crystal faces, strong hole oxidation capability and the like. As early as 2006, 2D BiOCl catalyst was reported to have excellent photocatalytic activity, which exhibited better activity than commercial P25 for degradation of Methyl Orange (MO) dye under both ultraviolet and visible light irradiation. And the band gap of BiOCl is about 3.2, and the visible light response is poor.
In order to overcome the defects of the BiOCl semiconductor, researchers have adopted a plurality of strategies to improve the efficiency of photocatalytic degradation of PPCPs, such as ion doping, morphology control, defect control, heterojunction system construction and the like. Wherein, controlling the BiOCl shape is a common and effective method. Patent CN201510642749.0 provides a method for preparing a BiOCl hollow shell by using a soft template, and has high application value in the fields of pollution control, new energy preparation, selective catalytic oxidation and the like. The ultrathin BiOCl nanosheet has the advantages of large specific surface area, strong adsorption capacity, multiple active sites, strong light absorption capacity, high separation efficiency of photon-generated carriers, high catalytic activity and the like, and is concerned in the field of photocatalytic research in recent years. So far, methods for preparing ultrathin BiOCl nanosheets with the thickness of several atomic layers mainly include hydrothermal solvothermal methods and high-temperature colloid chemical methods.
However, the high-temperature and high-pressure synthesis processes not only have high energy consumption, tedious process and long time consumption, but also need long-time high-speed centrifugal collection after the synthesis reaction is finished in order to obtain the ultrathin BiOCl nanosheet powder with small volume and light weight. The large-scale production and application of the ultrathin BiOCl nanosheet are severely restricted. Therefore, a synthetic method with low energy consumption, low cost and easy collection is needed to be developed, and the safe, green and macro preparation of the ultrathin BiOCl nanosheet is realized.
