摘要：

N-Doped meso-macroporous carbon materials were synthesized using melamine-formaldehyde resin as carbon precursor and silica spheres as a removable template. The as-synthesized carbon materials with a bimodal pores structure (about 3.9 and similar to 50-200 nm) display a high surface nitrogen content of 30 wt %. The macropores of carbon materials can be modulated by changing the diameter of template. The SO2 adsorption experiments demonstrate a high adsorption capacity of 78.6 mg g(-1) and a considerable stability even over 9 cycles for the carbon materials.
