钛基金属有机框架(Ti-MOFs)因其优异的热稳定性、化学稳定性、光催化活性及独特的晶体结构而在催化领域受到广泛的研究。由于Ti-MOF的合成困难,其优势难以得到展现,从而在应用方面受到限制。介绍了具有代表性的Ti-MOF的结构、合成方法,并详细讨论了Ti-MOFs在光催化分解水产氢、CO2还原、降解有机污染物及固氮等方面的应用,最后对应用方面固氮的机理进行了简单介绍。
Titanium-based metal-organic frameworks (Ti-MOFs) have been widely studied in the field of catalysis due to their excellent thermal stability,chemical stability,photocatalytic activity and unique crystal structure.Because of the difficulty in synthesizing Ti-MOFs,their advantages are hard to be demonstrated,thus limiting their application.This paper reviewed the structure and synthesis methods of representative Ti-MOFs,and discussed in detail the application of Ti-MOFs in the photocatalytic decomposition of aquatic hydrogen,CO2 reduction,degradation of organic pollutants and nitrogen fixation.Finally,the mechanism of nitrogen fixation in application was briefly introduced.
