合适的孔道大小和大量的金属位点在金属有机框架(MOFs:metal-organic frameworks)材料的应用中发挥着非常重要的作用.本研究通过选择性分解混组分 MOFs(STD of MC-MOFs:selective thermal decomposition of mixed-component MOFs)策略,使缺陷 MOFs中热稳定性差的部分选择性热分解掉,从而实现孔道和金属位点的双调节.与微孔的母结构Cu-BTC相比而言,所得的多级孔缺陷MOFs在燃油吸附脱硫实验中表现出更加优越的性能.
Thermal-Induced Defective MOFs with Hierarchical Pores and Their Application for Adsorptive Fuel Desulfurization
The appropriate pore size and a large number of metal sites play a very important role in the application of MOFs materials.This study employs the STD strategy of MC-MOFs to selectively decompose the component with worse thermal stability in defective MOFs,thereby achieving dual regulation of pore sizes and metal sites.Compared to the parent structure Cu-BTC,the obtained hierarchically porous defective MOFs exhibit better performance in adsorptive fuel desulfurization experiments.
