Problems solved by technology

However, the performance of organic porous materials still needs to be further improved
Before this invention, the reported hydrogen adsorption capacity of organic porous materials can reach up to 2.80wt% at low temperature and low pressure (1.0bar / 77K), but this adsorption capacity is far from the practical value, so the development of adsorption Organic porous materials with higher strength are very urgent for the storage of gases, especially hydrogen
