摘要：

Efficient, low-energy CO 2 capture technologies are crucial for reducing carbon emissions. However, conventional porous carbon materials typically suffer from low adsorption capacity, poor selectivity, and high energy consumption. In this study, polypyrrole carbon spheres were synthesized using pyrrole as both carbon and nitrogen sources, and nitrogen-doped ultramicroporous carbon materials (NPCS) were prepared through mechanical compaction assisted activation. Compared to NPCS700-0T (conventional activation), NPCS700-3T (mechanical compaction ...
