Description
Technical Field
The invention relates to a method for preparing a titanium-based metal organic framework homologous heterojunction photocatalyst.
Background
The micro-polluted organic matter is a general term for a class of organic pollutants which are widely present in an environmental water body in trace concentration (ng/L or mu g/L), and mainly comprises endocrine disruptors, personal care products, medicines and other emerging compounds. Antibiotics, one of the organic micropollutants, cause resistance to bacterial populations in the environment, and their toxicity, persistence and bioaccumulation enable them to accumulate progressively along the food chain, eventually entering the human and animal body and causing health hazards. A plurality of organic pollutants are brought into a priority control pollutant list in the United states and European Union, and the concentration limit value of part of organic pollutants is also regulated in the surface water environmental quality standard (GB 3838-2002) in China. The prior sewage treatment process is difficult to completely remove antibiotics, and a disinfection by-product is also generated in the treatment process of the conventional disinfection process. Therefore, the development of an antibiotic treatment technology which is economical, efficient and free from secondary pollution is urgently needed.
Because conventional processes are not effective in removing antibiotics, there are physical, biological and chemical methods of deep purification that are commonly used. In the physical treatment technology, the removal effect of the activated carbon adsorption and the membrane filtration on pollutants is good, the pollutants are stable and nontoxic by-products, but the pollutants are captured and are not harmless, and the cost for recovering the activated carbon and replacing the filtration membrane is high. However, the low biodegradability of organic pollutants causes the low efficiency of biological treatment methods, which is difficult to be applied in practice, so that the chemical oxidation method is a development trend of treating pollutants which are difficult to degrade. Among them, the advanced oxidation technology is favored because of its high reaction speed and high treatment efficiency, and can realize the thorough mineralization of pollutants. In particular, photocatalytic oxidation technology is considered as one of promising strategies for antibiotic treatment due to its low cost, high environmental efficiency, non-toxicity and stability. The ideal heterogeneous photocatalyst is the key to obtain excellent photocatalytic effect, and needs to have the characteristics of strong visible light absorption, high charge separation efficiency and long service life.
Traditional single heterogeneous system photocatalysts such as TiO2、Fe2O3And metal compound semiconductors such as ZnO and CdS have limited visible light absorption capacity, low adsorption capacity on antibiotics and high photo-generated charge recombination rate, so that the efficiency of photocatalytic degradation of pollutants is low. The construction of the composite photocatalytic system is an effective way for realizing efficient photocatalytic oxidation of pollutants. By selecting a proper narrow-bandgap semiconductor, the energy band structure of the semiconductor needs to meet the generation potential of free radicals, and the spectral response range of the semiconductor can be widened, so that sunlight is effectively utilized. While the heterocomposite structures (type II and Z) formed by band structure matching have proven to be an effective way to optimize the photocatalytic activity. In type II heterojunction catalysts, the redox capability of the photo-generated electron-hole pairs is impaired due to bandgap energy level matching and carrier transfer. The establishment of the Z-type heterogeneous composite structure is not only beneficial to the formation of photo-generated charges and the promotion of the separation and transfer of photo-generated carriers, but also can maximize the oxidation-reduction capability of electron-hole pairs. Therefore, the reasonable combination of the photocatalyst is the key for preparing the Z-shaped composite photocatalyst with high catalytic activity.
