作为肉类加工业的副产品，每年从牲畜、家禽和鱼类中产生近1亿吨的骨头、皮肤和鳞片，通常作为废物丢弃。然而，这些广泛且低成本的生物质材料富含主要由元素C、N、O和S组成的胶原蛋白。通过受控热解，这些富含胶原蛋白的生物质材料可以转化为生物质衍生的多孔碳（BPC）。有序的生物结构和天然前体的特定元素组成赋予BPC独特的纳米结构和杂原子掺杂，导致在电化学能量存储和转换中有前途的应用。特别是，来源于动物骨骼和鱼鳞的BPC由于其丰富的羟基磷灰石晶体而显示出新颖的孔隙率和形态，所述羟基磷灰石晶体充当天然存在的纳米结构模板。在这里，第一次审查集中在胶原蛋白衍生的多孔碳（CPC）的设计和合成。总结了不同类型CPC在电化学能量储存和转换中的具体应用。最后，对CPC的可控合成和大规模应用的挑战和前景进行了评估。
As byproducts of the meat‐processing industry, nearly 100 million tons of bones, skin, and scales are generated from livestock, poultry, and fish every year and are generally discarded as waste. However, these widespread and low‐cost biomass materials are rich in collagen that is primarily composed of the elements C, N, O, and S. By controlled pyrolysis, these collagen‐enriched biomass materials can be transformed into biomass‐derived porous carbons (BPCs). The ordered biotic structures and specific elemental compositions of the natural precursors endow BPCs with unique nanostructures and heteroatom doping, leading to promising applications in electrochemical energy storage and conversion. In particular, BPCs derived from animal bones and fish scales show novel porosities and morphologies due to their abundance of hydroxyapatite crystals, which act as naturally occurring nanostructured templates. Here, the first review focusing on the design and synthesis of collagen‐derived porous carbons (CPCs) is given. The specific applications of different CPCs in electrochemical energy storage and conversion are also summarized. Finally, the challenges and prospects for the controllable synthesis and large‐scale applications of CPCs are assessed.
