The obtained nitrogen- and sulfur-doped porous carbons (NSPCs) possess 3D hierarchical porous structure and contain a significantly high amount of N and S species. The concurrent incorporation of N and S successfully modified the surface properties of carbon materials and lead to enhanced capacitive performance. The presented NSPC exhibits specific capacitance of 230 F g(-1) at a current density of 1 A g(-1) and showed excellent cycling stability, depicting a promising material for energy storage devices.</p>1 aMehare, Rupali, S.1 aRanganath, Suresha, P.1 aChaturvedi, Vikash1 aBadiger, Manohar., V.1 aShelke, Manjusha, V.  uhttps://library.ncl.res.in/content/situ-synthesis-nitrogen-and-sulfur-enriched-hierarchical-porous-carbon-high-performance
