Sustainable biomass-derived porous carbons (BPCs) have attracted increasing attention in the past few years. The natural microstructures and specific compositions of biomass materials endow BPCs with novel nanostructures and abundant heteroatom doping, which can facilitate interfacial physical interactions and chemical reactions.<br/>Collagen-enriched waste materials (bones, skins, and scales from livestock, poultry, and fish) are promising precursors for the synthesis of advanced CPCs. The collagen-enriched precursors not only offer high abundance, low cost, and wide geographical distribution but also have abundant N and S atoms and natural templates. As alternatives to conventional activation and templating methods, several novel strategies have been designed for the efficient and controllable synthesis of CPCs with different morphologies (3D bulk, 3D network, and 2D nanosheets), porosities (hierarchical, micropore-dominant, and meso/macropore-dominant porosity) and compositions (abundant defects and N, O, and S heteroatoms). This unique combination of properties endows CPCs with excellent performance for symmetric capacitors, Li/Na-ion capacitors and electrochemical energy conversion (electrocatalysis of the oxygen reduction reaction, oxygen evolution reaction, and hydrogen evolution reaction).
