As part of ongoing efforts to realize a low-carbon and hydrogen-based society,there is an increasing demand for high-performance electrocatalysts, which arekey materials for fuel cells and water electrolysis systems. Although platinumgroup metals exhibit high catalytic activity, increasing production costs due toresource constraints, limited countries of production, and geopolitical supplyissues are threatening their use. Therefore, it is crucial to make substantialchanges in resource utilization for the sustainable production of electrochemicalcatalysts. Herein, the preparation of trifunctional biomass-derived electrocata-lysts for the oxygen reduction reaction and oxygen/hydrogen evolution reactionsby the pyrolysis of cellulose nanofibers from ascidian tunicates, dried blood meal,and cyanocobalamin is reported. The combination of N, P, FeN 4 , and CoN 4structures incorporated in the carbon network leads to high electrochemicalperformance comparable with rare-metal-based electrocatalysts and other carbonalloy electrocatalysts. This work provides a possible strategy for fabricating high-capacity energy storage devices from biomass resources such as industrial wastewithout the need for rare metals or other harmful heavy metals.
