Multifunctional ordered mesoporous carbon materials that feature high surface area, uniform pores, good conductivity of the carbon skeletons, and specific host‐gust interactions, which are of interest for a wide variety of applications, for instance, catalysis, photonics, bioscience, and energy storage, are presented. Here, we establish a facile and generalizable “coordination‐assisted self‐assembly” for encapsulation of aggregation‐free and highly dispersed metal nanoparticles inside the mesoporous carbon frameworks. The choice of pyrogallol as phenolic resin precursor is essential for the in situ encapsulation, because the strong coordination between the three hydroxide groups of pyrogallol and metal ions favors the immobilization of transition metal into the mesopores, and then suppress the sintering of metal nanoparticles at high carbonization temperatures. The metal supported mesoporous composites possess the very high loading content of 1.25 %–7.27 %, tiny particle sizes of 4.3–15.6 nm and high surface area of 475–589 m²/g. The unique structure in deed endows high sulfur loading content in the conductive mesoporous carbon channels, and meanwhile metal nanoparticles as catalyst effectively promotes the electrochemical conversion of polysulfides, resulting in a high reversible capacity, excellent rate capability and good cycling stability for Li−S batteries.

有序介孔碳中无聚集金属纳米粒子的配位-自组装方法

多功能有序介孔碳材料，具有高表面积，均匀的孔隙，良好的碳骨架导电性和特定的主机-阵风相互作用，是催化，光子学，生物科学和能源等广泛应用领域中关注的焦点存储，介绍。在这里，我们建立了一个简便且可推广的“配位辅助自组装”，用于将无聚集且高度分散的金属纳米颗粒封装在介孔碳框架内。选择邻苯三酚作为酚醛树脂前体对于原位包封至关重要，因为邻苯三酚的三个氢氧根与金属离子之间的强配位有利于将过渡金属固定在中孔中，然后抑制高碳化温度下金属纳米粒子的烧结。金属负载的介孔复合材料的负载量非常高，为1.25％–7.27％，微小颗粒尺寸为4.3–15.6 nm，高表面积为475–589 m² /克。行为的独特结构赋予了导电介孔碳通道中高的硫含量，同时金属纳米颗粒作为催化剂有效地促进了多硫化物的电化学转化，从而为Li-S电池提供了高可逆容量，出色的倍率性能和良好的循环稳定性。 。
