从可持续性的角度来看，使用木质素作为材料合成的前体现在被认为非常有趣。在这里，我们举例说明了使用通过碱性水热处理从山毛榉木中提取的木质素合成微孔、中孔和大孔氮掺杂碳（NDC），并通过芳香硝化连续功能化。由此获得的材料在共晶盐熔体KCl/ZnCl 2 中碳化。最终的 NDC 作为氧还原反应的电催化剂表现出优异的活性。
The use of lignin as a precursor for the synthesis of materials is nowadays considered very interesting from a sustainability standpoint. Here we illustrate the synthesis of a micro-, meso-, and macroporous nitrogen-doped carbon (NDC) using lignin extracted from beech wood via alkaline hydrothermal treatment and successively functionalized via aromatic nitration. The so obtained material is thus carbonized in the eutectic salt melt KCl/ZnCl2. The final NDC shows an excellent activity as electrocatalyst for the oxygen reduction reaction.
