The invention relates to a microalgal bio-based nitrogen-doped carbon material and a preparation method thereof. The method comprises the following steps: carbonizing microalgae for the first time toobtain semicoke, and carbonizing the semicoke for the second time in a nitrogen atmosphere to obtain the nitrogen-doped porous carbon material. The content of elemental nitrogen in the microalgal bio-based nitrogen-doped carbon material is 2.9 wt%, the specific surface area of nitrogen can reach 1893.26 m<2>.g<-1>, and the CO2 adsorption capacity at 0 DEG C can reach 5.72 mmol.g<-1> at most; and in a double-electric-layer supercapacitor system, specific capacitance can reach 335.7 F.g<-1> at most under the high current density of 1A.g<-1>. The microalgal bio-based nitrogen-doped carbon material can be used for adsorbing gas and manufacturing a double-electric-layer supercapacitor.
