| titleOfInvention |
A kind of porous organic framework material and its preparation method and application |
| abstract |
The invention relates to the field of porous organic framework materials, in particular to a porous organic framework material and a preparation method and application thereof. A new type of POFs material containing urea-based units was easily synthesized by the method of Biginelli polymerization. The new POFs material has abundant pore structure and stable structure, and has better adsorption effect on organic refractory pollutants. |
