Problems solved by technology

Choosing a rigid ligand with a larger size is conducive to the formation of a MOFs structure with high porosity. MOFs prepared by traditional hydrothermal methods will have a large amount of precipitation during the crystallization process, which needs to be cleaned with a solvent, and the post-processing operation process is complicated. The yield is low, and it is easy to form an interspersed structure with small or no pores, and the prepared product has poor adsorption performance
