Surface modification of biomass-based carbon with nitrogen-containing functional groups is performed by the different modification method, including the thermal and chemical methods. We also investigate the effect of the different reaction parameters on their pore structure using the Brunauer??“Emmett??“Teller surface area and adsorption performance based on methylene blue value. Fourier transforms infrared spectroscopy methods are performed to confirm the presence of N-containing groups. Based on above results, the comparison effect of different modification methods on physico-chemical propriety and adsorption properties of biomass-based carbon materials are carried out. In conclusion, all modification methods could enhance CO
