Finding sustainable, active, inexpensive, and stable electrocatalysts to replace Pt-based materials for the oxygen reduction reaction (ORR) remains a significant challenge. Here we report the use of functionalized lignin biomass as both carbon and dopant source for the direct synthesis of N and S dual-doped carbon sheet networks with abundant mesopores and high surface area. The resulting N and S-doped porous carbon exhibits good activity, long-term durability, and high selectivity for metal-free oxygen reduction electrocatalysis, approaching the performance of 20 wt% Pt/C, the state of the art ORR catalyst. Our method using natural biological resources thus offers a promising way to produce very promising noble metal-free ORR catalysts with potential application in alkaline fuel cells and metal–air batteries.

木质素磺酸盐生物质衍生的氮和硫共掺杂多孔碳，可实现有效的氧还原反应†

寻找可持续，活性，廉价和稳定的电催化剂来代替基于Pt的材料进行氧还原反应（ORR）仍然是一项重大挑战。在这里，我们报告功能化的木质素生物质作为碳和掺杂剂源的使用，用于直接合成具有丰富的中孔和高表面积的N和S双掺杂碳薄板网络。所得的N和S掺杂的多孔碳表现出良好的活性，长期耐久性以及对无金属氧还原电催化的高选择性，达到了20 wt％Pt / C（最先进的ORR催化剂）的性能。因此，我们使用天然生物资源的方法为生产非常有前途的无贵金属ORR催化剂提供了一种有前途的方法，并有望在碱性燃料电池和金属空气电池中应用。
