Three-dimensional carbon aerogels are attracting considerable attention because of their extraordinary fascinating features in terms of good electrical conductivity, large surface area, high porosity and good mechanical performance, which lead to a wide range of important potential applications. The thermal transformation of metal-organic framework (MOF) precursors is promising for the preparation of carbon materials. However, the resulting morphology of MOF-derived carbon has been largely determined by parent MOFs. Here, we present a self-templated and crosslinkers-free strategy for the synthesis of functionalized carbon aerogel with a highest surface area of 1916 m 2/g (pore volume around 5.19 cc/g) by versatile mechanical pressure and post-thermal transformation of parent MOFs, which break the dimensional limitation of MOF-derived carbon. The relationship between the structural transformation of MOFs precursors under the mechanical pressure and the variation of carbon materials in morphologies after post thermal transformation are investigated as well. As a carbon host matrix, pressure-induced monolithic carbon aerogels from MOFs were beneficial to load SnO 2 nanoparticles and this composites exhibit excellent capacities of 1420.7 mAh/g at 0.2 A/g and 850.5 mAh/g at 1 A/g, and outstanding rate capacity (514 mAh/g at even 5 A/g) for the lithium ion storage. Therefore, the excellent performance of these MOFs-derived carbon aerogels demonstrates that this synthetic approach can produce functional matrix materials for lithium ion batteries (LIBs).

三维碳气凝胶以其出色的导电性，大表面积，高孔隙率和良好的机械性能而引人注目，因而引起了广泛的关注，这引起了广泛的重要潜在应用。金属有机骨架（MOF）前体的热转化有望用于制备碳材料。但是，MOF衍生碳的形态在很大程度上由母体MOF确定。在这里，我们提出了一种通过自我模板化和无交联剂的策略，通过通用的机械压力和热后转化，可以合成表面积最大为1916 m 2 / g（孔体积约为5.19 cc / g）的功能化碳气凝胶。母MOF，打破了MOF衍生碳的尺寸限制。还研究了MOFs前驱体在机械压力下的结构转变与后热转变后碳材料形态变化之间的关系。作为碳基质，来自MOF的压力诱导的整体式碳气凝胶有利于负载SnO 2纳米颗粒，并且该复合材料在0.2 A / g时表现出1420.7 mAh / g的优异容量，在1 A / g时表现出850.5 mAh / g的优异容量，并且表现出色锂离子存储的最大容量（514 mAh / g，甚至5 A / g）。因此，这些源自MOF的碳气凝胶的出色性能表明，这种合成方法可以生产锂离子电池（LIB）的功能性基质材料。
