【 摘 要 】

tsThe N/S co-doped lignin-derived porous carbon (NSLPCs) with ultra-high heteroatom doping was prepared through a novel supramolecule-mediated pyrolysis strategy.Covalently bonded graphitic carbon/amorphous carbon intermediates induce the formation of high heteroatom doping.The high heteroatom doping of NSLPC could provide abundant defective active sites for the adsorption of K+.
