摘要：

Highly ordered mesoporous carbon nitrides (MCN) with 3D structure and a high nitrogen content are successfully prepared for the first time using "uncalcined" mesoporous silica template, KIT-6 and 3-amino-1,2,4-triazole as a single molecular carbon and nitrogen precursor. The prepared MCN with C and N stoichiometry of C3N5 shows unique CN framework and exhibits the CO2 capture capacity of 5.63 mmol g(-1) at 273 K and 30 bar, which is higher than that of MCN with 2D structure and C3N4 stoichiometry.
