Description

Composite photocatalyst and preparation method thereof
Technical Field
The invention relates to a catalyst, in particular to a composite photocatalyst.
Background
Energy and environmental problems are two serious problems faced by the current society, and the development of the society is seriously restricted. Among the technical means, photocatalysis is considered as the most promising method for solving the energy and environmental problems due to the characteristics of low energy consumption, environmental friendliness and high efficiency. Metal-organic frameworks (MOFs) are three-dimensional, reticulated porous materials formed by self-assembly of Metal central ions and organic ligands. The nano-porous silicon dioxide has the advantages of large specific surface area, high porosity, good stability, adjustable topological structure and the like, so that the nano-porous silicon dioxide is widely researched and applied to the fields of gas separation and storage, drug delivery, catalysis, luminescent materials and the like. The photocatalysis technology is a new technology for high-efficiency pollutant degradation, can promote the formation of non-spontaneous reaction by the power of sunlight, is safe and non-toxic, has the unique advantages of mild reaction conditions, unlimited treatment load, no selectivity in pollutant treatment and the like, and plays a great charm in the field of environmental protection. However, in the aspect of water treatment, the effective catalytic degradation process of the photocatalytic material can only be performed under ultraviolet light, so that the application of the photocatalytic material is greatly restricted, and the catalytic degradation cost is increased. Most MOFs have a wide energy band gap, which results in absorption of only about 5% of the total sunlight, and this has a significant limitation in practical applications. In fact, of the solar radiation, infrared and near-infrared radiation account for 53%. Therefore, in photocatalysis, how to fully utilize infrared light and near infrared light in sunlight has great research value.
Graphite phase carbon nitride (g-C)3N4) As a carbon-based material, the material has the characteristics of wide sources of preparation raw materials, low price, simple preparation method, easy industrialization and the like. The photocatalyst has adjustable electronic structure and good physical and chemical stability. The forbidden band width of the material is 2.70eV, so that the material can be excited by visible light and can absorb the visible light to decompose water to prepare hydrogen. However, g-C3N4Also has many disadvantages to improve the photocatalytic performance, especially higher electron hole recombination rate, seriously reducing the photocatalytic efficiency, and improving g-C3N4The photocatalytic performance and the improvement of the electron hole separation rate are always the key points of research in the field.
MoS2Is a two-dimensional ferrous metal sulfide with metallic luster. It consists of two S atoms and one Mo atom layer as the middle layer2The special structure has extremely high transmission rate of carriers in the structure, and the energy band width range of the structure is 1.2-1.9eV, so that the structure can absorb more sunlight and has extremely high utilization rate of the sunlight. The material has excellent electrical and optical characteristics, and is widely applied to the fields of microelectronic devices, solar cells and the like at present. MoS2The active sites for the photocatalytic reaction are located at the edges of the exposed S-Mo-S layer in the layered structure. MoS2Less conductive and prone to layer-by-layer stacking with reduced edge exposure to active sitesThereby reducing its photocatalytic activity. One solution to this problem is to use MoS as a solution2Dispersed on a suitable template material to prepare high-sulfur multi-edge MoS2A material.
A modified MoS is disclosed in patent CN 106975511A2/g-C3N4The photocatalyst disclosed by the patent can be used for carrying out catalytic degradation on rhodamine B under the irradiation of near infrared light, but the catalytic efficiency is lower. In patent CN 107115880A, a MoS is disclosed2/CNTs/g-C3N4The composite photocatalytic material and the preparation method thereof, but new pollution is introduced by residual metal ions of nickel and chromium of the carbon nano tube while rhodamine B is degraded, and the problem of recovery is difficult to solve. In is disclosed In patent CN 103990486A2S3/g-C3N4The preparation method of the composite nano material is that In the experiment of degrading Methylene Blue (MB), the composite photocatalyst has a single In ratio2S3Has better catalytic effect, but g-C3N4The preparation of the urea is obtained by calcining urea at the high temperature of 550 ℃, and the preparation process is complex, has high cost and is not beneficial to energy conservation and environmental protection.

It effectively retains MoS2The wide absorption property and the wide light response range can greatly improve the utilization rate of light. And the structural integrity of the ZIF-8 is well reserved, so that the composite photocatalytic material has a higher specific surface area, can have good adsorption performance, provides enough active sites for photocatalytic reaction, and effectively improves the photocatalytic effect of the photocatalystAnd (4) rate. When g-C3N4And MoS2When the light is irradiated by visible light, electrons on the valence band are excited and jump to the conduction band, so that photo-generated electron-hole pairs are generated. And because of g-C3N4The conduction band potential of (A) is more negative, so that photogenerated electrons on the conduction band can be transferred to the MoS2And ZIF-8 conductive band, the transferred electrons react with dissolved oxygen in the reaction system to generate active substance of superoxide radical (. O)2 -) The superoxide radicals can react with MB dye molecules adsorbed on the surface of the composite photocatalyst, and play a role in degrading MB through photocatalysis. And MoS2So that its hole can migrate to g-C3N4The holes are able to directly degrade MB.
(2) The preparation method of the invention fully uses microwave heating to accelerate the nucleation rate and the crystal growth rate. The microwave method has the advantages of short reaction time, high yield, simple equipment, low pollution, no temperature gradient, small size of the synthesized product and uniform particle size distribution. Using thioacetamide and urea as g-C3N4The synthetic universality is that an S-S coupling bond is formed on the interface, which is beneficial to improving the interface combination degree and improving the electron conduction rate. Therefore, compared with the room-temperature self-assembly method and the hydrothermal method, the method has greater innovation in theory and technology.
