Nitrogen- and phosphorus-co-doped carbons with tunable enhanced surface areas promoted by the doping additives

摘要

1-Butyl-3-methyl-pyridinium-dicyanamide (BMP-dca) is carbonised with tetra-alkyl-phosphonium-bromide additives yielding nitrogen-and phosphorus-co-doped carbons with enhanced BET surface areas promoted by the additives. Heteroatom doping of carbon materials is an emerging field of materials science. Nitrogen is by far the most prominent doping candidate and numerous examples with versatile applications, e.g. in electrochemistry, are known. Although other heteroatoms are of thriving interest, synthetic pathways towards boron-, sulphur- and phosphorus-doped carbons are still rare.
