Mild and Efficient One-Step Synthesis of Nitrogen-Doped Multistage Porous Carbon for High-Performance Supercapacitors.

ABSTRACT: Biomass-derived carbon materials have broad application prospects in energy storage, but still face problems such as complex synthesis paths and the massive use of corrosive activators. In this study, we proposed a mild and efficient pathway to prepare nitrogen-doped porous carbon material (N-YAC) using one-step pyrolysis with solid K₂CO₃, tobacco straw, and melamine. The optimized material (N-YAC_0.5) was not only enriched with nitrogen, but also exhibited a high specific surface area (2367 m²/g) and a reasonable pore size distribution (46.49% mesopores). When utilized in electrodes, N-YAC_0.5 exhibited an excellent capacitance performance (338 F/g at 1 A/g) in the three-electrode system, and benefitted from a high mesopore distribution
