Description
Technical Field
The invention belongs to the field of preparation of photocatalytic materials and technology, and particularly relates to a MI L-100 (Fe) metal organic framework material doped with different metals, a preparation method thereof and application thereof in photocatalytic nitrogen fixation.
Background
Ammonia is an extremely important chemical raw material and is widely used in a plurality of fields. In the traditional industrial synthesis of ammonia, the synthesis is mainly carried out by nitrogen and hydrogen under the condition of catalyst at high temperature and high pressure for a long time. Has the disadvantages of high cost, low reaction efficiency, high energy consumption, harsh reaction conditions, etc. Therefore, the method for producing the synthetic ammonia, which is economic, efficient and environment-friendly under mild conditions, has great significance. Therefore, further exploration of new synthetic methods has attracted much attention from researchers. In recent years, new ideas of biomimetic enzyme catalysis nitrogen fixation, photocatalysis nitrogen fixation and the like are continuously researched and developed, which opens up a new way for the synthetic ammonia industry. However, the development is limited by the complexity of the enzyme structure and the difficulty of synthesis. In addition, in the method for synthesizing ammonia by catalyzing nitrogen gas by using the semiconductor photocatalyst, most of the semiconductor catalysts cannot activate nitrogen gas molecules due to the ultrahigh stability of the nitrogen gas molecules, and show low yield or no product. If a bionic photocatalyst can be designed by combining the excellent reaction conditions of photocatalysis and the structural property of enzyme, nitrogen can be better activated to synthesize ammonia. The metal organic framework material has a structure similar to that of enzyme and has good application in the field of photocatalysis, and the metal organic framework material just meets the conditions. Based on the analysis, a suitable metal organic framework material is designed to be used as a catalyst to activate nitrogen, and light is used as clean energy to drive the reaction of the nitrogen to be converted into ammonia, so that the method is economic and environment-friendly and has a great prospect.
MI L-100 (Fe) is used as a typical metal organic framework material, has a plurality of excellent properties such as no toxicity, economy, easy obtaining, environmental friendliness, stable properties and the like, and is applied to the fields of photolysis of water, photodegradation of pollutants and the like, however, the single MI L-100 (Fe) has no activity on photocatalysis nitrogen fixation, so according to the current research progress, the structure of MI L-100 (Fe) is regulated and controlled to activate nitrogen, Ni is used as a transition metal element, and the excellent catalytic performance is widely applied to industrial catalysis due to the atomic orbital characteristics of the Ni, therefore, metal M (M = Cd, Mn, Co, Ni, Cu and Ag) is selected to carry out doping modification on MI L-100 (Fe), so that the MI L-100 (Fe) has two metals with different empty orbital acting forces, Fe and M, the nitrogen triple bond balance of nitrogen molecules is destroyed by using the different acting forces of the two metals on electrons, the metal Fe is further activated by using the nitrogen as an energy source, the activated nitrogen molecules are converted into ammonia, and the metal Fe is used for providing a good high-nitrogen-triple bond-nitrogen-enriched material, and the high-nitrogen-enriched and the high-nitrogen-enriched organic-nitrogen-enriched material is used for the research of the industrial catalysis, and provides a good high-enriched metal-enriched and the high-enriched metal-enriched organic-enriched organic-enriched.
