摘要
在这项研究中，我们利用干血粉和取自海菠萝壳的纤维素纳米纤维 (CNF) 合成了一种生物质衍生碳合金催化剂，称为 "纳米血炭 (NBC)"。这种催化剂在中性条件下表现出很高的活性，并成功制造出一种高输出、环保的水激活镁空气纸电池。电池的开路电压（OCV）为 1.57 V，最大电流密度为 161 mA cm-2。最大功率密度为 55.7 mW cm-2，单个纸电池的容量为 749 mW h g(Mg)-1。此外，还评估了 NBC 的氧进化反应（OER）性能，为实现可充电镁-空气纸电池做出了贡献。
Sustainable water-activated metal–air paper batteries based on waste biomass-based electrocatalysts†
In this study, we synthesized a biomass-derived carbon alloy catalyst, termed “nano-blood charcoal (NBC),” using dried blood meal and cellulose nanofibers (CNFs) sourced from sea pineapple shells. This catalyst demonstrated high activity under neutral conditions and enabled the successful fabrication of a high-output, environmentally friendly water-activated magnesium–air paper battery. The open circuit voltage (OCV) of the cell was 1.57 V, and the maximum current density was 161 mA cm−2. The maximum power density was 55.7 mW cm−2, and the capacity of a single paper battery cell was 749 mW h g(Mg)−1. Additionally, the oxygen evolution reaction (OER) performance of NBC was also evaluated, and it contributed to realize a rechargeable Mg–air paper battery.
