摘　　要：有序介孔碳材料由于其较大的表面积、均一的孔径、良好的热稳定性和化学稳定性,广泛应用于吸附、分离、催化以及能量储存等众多领域。与传统的以硅基介孔材料为硬模板的反向复制方法相比,通过嵌段共聚物和聚合物前驱体之间的有机-有机自组装的软模板法简便易行,已成为合成有序介孔碳材料有效方法。本论文综述了介孔碳材料的软模板合成机制、合成方法、功能化及其应用,对合成技术、结构控制、孔径调控以及形貌控制等方面进行了讨论,并探讨了其在吸附、催化、电极材料等领域的应用。Ordered mesoporous carbon materials have attracted great research interests due to their extremely large surface area,uniform pore size,high thermal stability and chemical inertness,w hich have been w idely used in the areas including catalysis,adsorption,energy storage and conversion. The direct synthesis strategy from organic-organic self-assembly involving the combination of polymerizable precursors and block copolymer templates is expected to be more flexible in preparing mesoporous carbons,compared w ith the traditional nanocasting strategy of fussy and high-cost procedures using mesoporous silica materials as the hard template. In this critical review,w e present the fundamentals and recent advances related to the researches of ordered mesoporous carbon materials from the direct synthesis strategy of block copolymer soft-templating,w ith a focus on their controllable preparation,modification and potential applications. Under the guidance of their formation mechanism,the preparation of ordered mesoporous carbons are detailedly discussed by synthetic pathw ays, including evaporation induced self-assembly method,dilute aqueous route,macroscopic phase separation and hydrothermal autoclaving process. The mesopore size and morphology control,and the hybrid carbon materials are also demonstrated. The potential applications of pure and modified mesoporous carbons in adsorption,catalysis and electrochemistry are detailed discussed. Furthermore,remarks on the challenges and perspectives of research directions are proposed for further development of ordered mesoporous carbons.
