摘要
通过对生物质浮萍进行简单的热解碳化和碱活化制备了氮磷共掺杂多孔碳板（NPCP），NPCP 的最大比表面积（SSA）为 2023 m2 g-1，且富含吡啶 N 和 P 掺杂，这使得无金属碳具有优异的电催化氧还原性能。最好的 NPCP2 在碱性电解液中对 Ag/AgCl 的半波电位为 0.19 V，其活性与商用铂碳（Pt/C）相当。此外，它还具有优异的耐甲醇毒性和持续催化稳定性。实验结果表明，生物质水培法获得的杂原子掺杂方法在多孔碳材料催化领域具有很大的优势和应用价值。
Biomass N/P co-doped porous carbon plates for electrocatalytic oxygen reduction
Nitrogen and phosphorus co-doped porous carbon plate (NPCP) was prepared by simple pyrolysis carbonization and alkali activation of biomass duckweed NPCP displays the largest specific surface area (SSA) of 2023 m2 g−1, and is rich in pyridine N and P doping, which makes the metal-free carbon have excellent electrocatalytic oxygen reduction performance. The best NPCP2 shows a half-wave potential of 0.19 V vs. Ag/AgCl in alkaline electrolyte, and its activity is equivalent to that of commercial platinum carbon (Pt/C). In addition, it shows excellent methanol toxicity resistance and continuous catalytic stability. The experimental results show that the heteroatom doping method obtained by biomass hydroponics has great advantages and great application value in the catalytic field of porous carbon materials.
