文摘
- •
Developed porous covalent triazine–piperazine linked polymer with 3D nanoflower microstructure.
- •
The nanoflower microstructure was fashioned by the self-assembly of interwoven and slight bent nanoflake components.
- •
Material having Lewis base enrich-sites and exhibited outstanding chemical robustness and thermal stability.
- •
Materials acts as an adsorbents and showed enhance CO2 and CH4 uptake and high CO2/N2 and CH4/N2 sorption selectivity.
- •
Single-component gas adsorption study and binary gas mixture breakthrough experiment validated the material as a promising adsorbent for environmental remediation.
