Dicyandiamide (DCDA) was utilized as a facile nitrogen source for the fabrication of nitrogen-containing ordered mesoporous carbon (NOMC) samples via a one-pot soft-templating approach under aqueous phase. X-ray diffraction, N₂ adsorption–desorption, Transmission electron microscopy, Scanning electron microscopy, Raman and X-ray photoelectron spectroscopy have been applied to analyze the physicochemical properties of the synthesized NOMC materials. The characterization results showed that the textural parameters (545–589 m² g⁻¹), graphitic crystallinity and distribution of various nitrogen species of the synthesized NOMC materials were largely dependent on the adding mass of DCDA. Besides DCDA, NOMC materials have been also successfully fabricated by employing urea and melamine as nitrogen sources. As metal-free heterogeneous catalysts, the NOMC materials showed good catalytic activity and selectivity in the transesterification of ethylene carbonate to dimethyl carbonate, affording a maximum yield of dimethyl carbonate up to 76 % at 3 h under 120 °C.

双氰胺（DCDA）被用作一种简便的氮源，用于在水相下通过一锅法软模板法制备含氮有序介孔碳（NOMC）样品。X射线衍射，N ₂吸附-解吸，透射电子显微镜，扫描电子显微镜，拉曼光谱和X射线光电子能谱已用于分析合成的NOMC材料的理化性质。表征结果表明，织构参数（545–589 m ²  g ^-1），合成的NOMC材料的石墨结晶度和各种氮物种的分布在很大程度上取决于DCDA的添加量。除DCDA外，还通过使用尿素和三聚氰胺作为氮源成功地制造了NOMC材料。作为无金属的多相催化剂，NOMC材料在碳酸亚乙酯酯交换成碳酸二甲酯方面表现出良好的催化活性和选择性，在120°C下3 h时碳酸二甲酯的最大收率高达76％。
