Nitrogen containing functional groups of biochar: An overview

[Display omitted] •Pyridinic-N, pyrrolic-N, and quaternary-N dominate biochar N-functional groups.•N-functional groups of biochar can be analyzed by FTIR, XPS, NMR and XANES.•N-functional groups are mainly results of biomass, pyrolysis temperature & N-doping.•Biochar N-functional groups favor po...
