Three-dimensional porous nitrogen-doped carbon materials with extra high nitrogen content produced by directly carbonizing nitrogen-enriched precursors for supercapacitors.
This study deals with the one-step facile synthesis of Fe1-xS nanoparticle-containing nitrogen-doped porous carbon membranes (denoted as Fe1-xS/N-PCMs) via vacuum carbonization of hybrid porous poly(ionic liquid) (PIL) membranes, and their...
