The combined template of Mn(CH₃COO)₂, KCl, and CO(NH₂)₂ is a strategy for the structural control and functionalization of porous carbons. Waste peach gum is used to achieve the orderly design of N, O-codoped lamellar porous carbon (NLPC). The prepared carbon electrode obtains a mass specific capacitance of 402 F g^–1 at an ampere density of 0.5 A g^–1 in 6 M KOH, long cycle stability (99.5% mass specific capacitance retained after 10000 cycles), and rich surface heteroatoms (O is 9.53 at. %, N is 14.04 at. %). In addition, the prepared symmetrical supercapacitor (NLPC-700//NLPC-700) has excellent cycle life (99.1% specific capacitance). Therefore, this work proposes a design of integrating heteroatom doping and pore size engineering into carbon materials that can branch out to other fields such as energy storage and energy conversion.

通过生物衍生的纳米孔结构对对称超级电容器进行电极材料的适当设计

Mn（CH ₃ COO）₂，KCl和CO（NH ₂）₂的组合模板是用于多孔碳的结构控制和功能化的策略。废桃胶用于实现N，O掺杂的层状多孔碳（NLPC）的有序设计。准备好的碳电极在0.5 A g ^–1的安培密度下可获得402 F g ^–1的质量比电容在6 M KOH中，长循环稳定性（10000次循环后保留了99.5％的质量比电容）和丰富的表面杂原子（O为9.53 at。％，N为14.04 at。％）。此外，制备的对称超级电容器（NLPC-700 // NLPC-700）具有出色的循环寿命（比电容为99.1％）。因此，这项工作提出了一种将杂原子掺杂和孔径工程集成到碳材料中的设计方案，该材料可以扩展到其他领域，例如能量存储和能量转换。
