In recent years, the nano semiconductor photocatalysis technology has attracted wide attention due to the great advantages of the nano semiconductor photocatalysis technology in the aspects of alternative energy and environmental remediation, and is also applied to industrial production. A wide variety of semiconductor photocatalytic materials such as TiO2CdS, ZnO and different morphological structures such as flower-like (SnWO)4) Rod-like (ZnO), sheet-like (BiVO)4) The binary metal oxide of (A) has a certain application in the field of photocatalysis. However, TiO2The photocatalyst such as ZnO has a wider band gap structure, has stronger response to ultraviolet light only and lower utilization rate to natural light, so that the special properties of other materials and TiO are utilized2The photocatalyst is compounded, so that the improvement of the photocatalytic performance becomes a new research hotspot.
At present, metal sulfides such as Sb2S3、Bi2S3Due to the narrow band gap structure, it has attracted a wide attention to have a strong response in the visible region. Among numerous binary metal sulfides, the direct band gap semiconductor material Sb belonging to the orthorhombic system2S3Due to strong spectral response, higher thermal band energy and excellent photoelectric property, the photocatalyst is widely applied to the fields of solar energy conversion, photocatalysis, thermoelectric cooling and the like, and simultaneously is used as a photocatalyst together with TiO2Compared with ZnO, the photocatalyst has higher photocatalytic degradation efficiency in a visible light region. Sb2S3The main disadvantages of (1) are that photogenerated electron-hole pairs are easy to recombine and the electron migration rate is slow. Increase of Sb2S3The improvement of the separation efficiency by utilizing the oxidation mechanism of electron hole pairs in water is considered as the key for effectively degrading organic pollutants, so that the design of the composite material for effectively reducing the recombination rate of photo-generated electron holes becomes a research hotspot. To promote Sb2S3Efficient separation of photogenerated carriers, some semiconductor materials (TiO)2ZnO) or conductor materials (rGO, carbon nanotube CNT) and Sb2S3Composite, as an electron transfer acceptor, greatly improves Sb2S3The photon-generated carrier migration rate and the separation efficiency.
The latest research found that MoS2As a two-dimensional (2D) layered material similar to graphene, attention is paid to its layered structure, in which each layer is formed of two hexagonal close-packed S atoms and one Mo atom in between to form a sandwich structure, adjacent layers are bonded together by weak van der waals force, MoS2The layered structure shows huge specific surface area and more active sites, so that the layered structure has certain adsorption performance and also provides rapid migration of electronsIt is possible. As a member of a transition metal disulfide (MX)2M represents transition metal, X represents chalcogenide metal such as S, Se, Te and Po), the band gap of the chalcogenide metal is 1.23-1.69 eV, the solar light utilization rate is high, and the band gap is related to factors such as layer thickness, nanometer size and doping. MoS2The crystal phase of (A) is mainly hexagonal phase 2H-MoS2Orthorhombic 3R-MoS phase2Tetragonal phase 1T-MoS2。MoS2The properties of the catalyst can be widely applied to a plurality of aspects such as sensors, super capacitors, solar panels, catalytic hydrogen production and the like, and can be used as a cocatalyst for degrading organic wastewater. Mixing MoS2And Sb2S3The composite photocatalyst is prepared by compounding, and not only can exert Sb2S3Can exert strong absorption effect on visible light and strong photocatalytic activity thereof, and can also exert MoS2The function of (1): (1) as an excellent electron transporter, the photocatalyst can efficiently prevent the self-phase recombination of electron hole pairs in the photocatalysis process so as to improve the catalytic performance of the photocatalyst; (2) mixing MoS2The photocatalyst is compounded with the photocatalyst, so that the light absorption intensity of the photocatalyst can be improved, and the absorption wavelength range of sunlight is expanded, so that the solar energy utilization rate is improved; (3) MoS with huge specific surface area2The photocatalyst carrier can increase the specific surface area of a semiconductor, so that the adsorption sites and the catalytic sites of the composite material are increased, and finally, the catalytic performance of the photocatalyst is enhanced. Simultaneously, MoS2And Sb2S3Compounding also helps to reduce MoS2The self-phase stacking phenomenon is more beneficial to the dispersion of the photocatalyst. Thus, Sb2S3And MoS2The composite photocatalyst has wide research prospect.
