On behalf of solving the problem of phenol pollution in water environment, Fe/N co-doped porous hydrochar (Fe-N-PHC) as environmentally friendly catalyst prepared by agricultural waste bamboo shoot shells (BSS) as biomass was utilized to activate persulfate (PS) on phenol degradation. Under optimal reaction conditions, the degradation efficiency of phenol in Fe-N-PHC/PS system could achieve 100 % within 60 min, which was much higher than that of PHC/PS system (43.6 %). The significant role of N and Fe species for phenol degradation was confirmed by XPS analysis. Notably, Fe-N-PHC had a rich pore structure, CO and pyrrolic N as active sites were in favor of producing reactive oxygen species (ROSs). At the same time, the edge defects and pyridine N on Fe-N-PHC played a role in enhancing electron transfer. In addition, Fe cycle occurred on Fe-N-PHC surface contributed to PS activation for phenol removal. Results showed that Fe-N-PHC/PS system had high reusability, strong adaptability in different pH (3.0–11.0), co-existing substances and water bodies, and the degradation efficiency of phenol was maintained above 75 %. This study enriched the way of agricultural waste resource utilization, and provided an economical and feasible method for innovatively preparing eco-friendly carbon-based catalysts for water pollution remediation.

以农业废弃竹笋壳(BSS)为生物质制备的Fe/N共掺杂多孔碳氢炭(Fe-N-PHC)作为环保催化剂，代表解决水环境中苯酚污染问题，用于活化过硫酸盐( PS）对苯酚降解的影响。在最佳反应条件下，Fe-N-PHC/PS体系对苯酚的降解效率可在60 min内达到100%，远高于PHC/PS体系（43.6%）。 XPS 分析证实了 N 和 Fe 对苯酚降解的重要作用。值得注意的是，Fe-N-PHC具有丰富的孔隙结构，CO和吡咯N作为活性位点有利于产生活性氧（ROS）。同时，Fe-N-PHC上的边缘缺陷和吡啶N起到了增强电子传递的作用。此外，Fe-N-PHC表面发生的Fe循环有助于PS活化以去除苯酚。结果表明，Fe-N-PHC/PS体系重复使用性高，对不同pH值（3.0~11.0）、共存物质和水体适应性强，对苯酚的降解效率均保持在75%以上。该研究丰富了农业废弃物资源化利用途径，为创新制备生态友好型碳基催化剂用于水污染修复提供了经济可行的方法。
