我们报道了利用蒸发诱导自组装（EISA）方法合成可持续有序介孔碳（OMC）。我们证明，它是可能的，以取代一半的间苯三酚（一个众所周知的碳前体，目前不来自生物前体）的硬木有机溶剂木质素，同时获得高度有序的孔结构。值得注意的是，我们还使用乙二醛代替甲醛作为交联剂，这使得合成路线在前体的毒性及其可再生来源方面更加“绿色”。最后，我们证明了所得碳在超级电容器中形成强大的电极，并且我们已经在对称超级电容器中明确了多孔结构与其电化学性能之间的相关性，以便提供定制的能量存储以满足各种需求（即存储的电荷量与输送功率）。
We report the synthesis of sustainable ordered mesoporous carbons (OMCs) produced from lignin, using the evaporation induced self-assembly (EISA) method. We demonstrated that it is possible to replace half of the phloroglucinol (a well-known carbon precursor currently not derived from bioprecursors) by hardwood organosolv lignin while obtaining a highly ordered pore structure. Notably, we also used glyoxal instead of formaldehyde as a crosslinker, which makes the synthesis route even "greener" with respect to the toxicity of the precursors and their renewable sourcing. Finally, we demonstrated that the resulting carbons make powerful electrodes in supercapacitors and we have made clear correlations between the porous structure and their electrochemical performance in symmetric supercapacitors in order to deliver tailored energy storage to meet various demands (i.e. amount of charge stored vs. power of delivery).
