Biomass‐derived carbon aerogels refer to carbon aerogels prepared using biomass as the precursor. They are environmentally friendly, cheap and have abundant precursors, which have aroused widespread interest and exhibit excellent performance in the fields of electrocatalysis (e. g. for the hydrogen evolution, oxygen evolution and oxygen reduction reactions) and energy storage (i. e. as electrode materials for supercapacitors). Furthermore, metal species can be incorporated into the porous carbon matrix without destroying the original 3D structure whilst improving its conductivity and electrochemical performance. Above all, most biomass materials contain nitrogen functionalities, and can be doped in situ (self‐doping) with heteroatoms, such as N, without any additives, thereby creating additional defects and active centers with augmented electron density and electron‐contributing attributes. Herein, the electrochemical applications of biomass‐derived carbon aerogels reported during the last decade, especially in the field of water electrolysis, metal‐air batteries, fuel cells and supercapacitors, are summarized. Current research challenges and future directions are briefly highlighted.

生物质氮掺杂碳气凝胶在电催化和超级电容器中的应用

生物质衍生的碳气凝胶是指以生物质为前体制备的碳气凝胶。它们环保，便宜并且具有丰富的前驱物，引起了广泛的兴趣，并且在电催化（例如，析氢，析氧和氧还原反应）和能量存储（例如，用作超级电容器的电极材料）领域表现出优异的性能。。此外，可以在不破坏原始3D结构的同时将金属物种掺入多孔碳基质中，同时改善其导电性和电化学性能。最重要的是，大多数生物质材料都具有氮功能，并且可以在不添加任何添加剂的情况下原位掺杂（自掺杂）杂原子（例如N），从而产生额外的缺陷和具有增强的电子密度和电子贡献属性的活性中心。本文总结了近十年来生物质衍生的碳气凝胶的电化学应用，特别是在水电解，金属空气电池，燃料电池和超级电容器等领域。简要强调了当前的研究挑战和未来的方向。
