Abstract:2D carbon materials like graphene and carbon nanosheets excel in energy storage and conversion due to their unique microstructure, pores, and electrochemical properties. Our study successfully synthesized coal-based 2D ultrathin N-doped hierarchical porous carbon nanosheets (NCPNs) using a dual-salt system of Na 2 CO 3 −K 2 CO 3 for high-performance supercapacitors (SCs). To achieve this, we used coal and urea as carbon and nitrogen sources, respectively, with K 2 CO 3 as an activator and Na 2 CO 3 as a templa… Show more
