纳米结构碳材料如富勒烯和碳纳米管的发现引起了人们对各种碳质材料开发的极大兴趣。有序介孔碳（OMC）的最常见的合成路线涉及多步合成过程，其中有序介孔二氧化硅用作硬模板。相比之下，我们的新型OMC合成路线避免了使用硬模板，并且可以减少制备步骤的数量和生产这些材料所涉及的成本。我们的策略是利用热固性聚合物和可热分解的表面活性剂之间的有机-有机相互作用来形成周期性有序的纳米复合材料。热固性聚合物通过在N2下加热而固化，在该过程之后，其保持为碳质孔壁。间苯二酚/甲醛（RF）和原乙酸三乙酯（EOA）用作碳共前体，三嵌段共聚物Pluronic F127用作表面活性剂（图1C）。
The discovery of nanostructured carbon materials such as fullerenes and carbon nanotubes has led to a considerable interest in the development of various carbonaceous materials. The most common synthetic route yielding ordered mesoporous carbons (OMCs) involves a multi-step synthetic procedure, in which ordered mesoporous silicas are employed as hard templates. In contrast, our novel OMC synthesis route avoids the use of hard templates, and could reduce the number of the preparation steps and the cost involved in producing these materials. Our strategy is to use an organic– organic interaction between a thermosetting polymer and a thermally-decomposable surfactant to form a periodic ordered nanocomposite. The thermosetting polymer is carbonized by heating under N2, after which process it remains as a carbonaceous pore wall. Resorcinol/ formaldehyde (RF) and triethyl orthoacetate (EOA) were used as a carbon co-precursors and triblock copolymer Pluronic F127 was used as a surfactant (Fig. 1C).
