输出（10 面板记录）
面板 1： 论文类型与核心论点
Research paper. First discovery of wood as a bifunctional electrode for CO2RR (FE 70.8% at -1.8V, j=53.8 mA/cm2) and electroanalytical sensing (Abstract, Section 1).
面板 2： 研究问题与系统设计
Can pure carbonized wood (without N/B/metal doping) intrinsically catalyze CO2RR to formate? Design: Natural wood carbonization → three-electrode H-cell → 1H NMR product analysis + N2 control.
面板 3： 方法深入
Characterization: SEM (microchannels), BET (182 m2/g, mesoporous), XRD (24.1deg, 002), Raman (ID/IG=1.12), XPS (C 95.74%, O 4.26%). Testing: LSV 20mV/s, constant-potential electrolysis, DPV/DPASV for sensing.
面板 4： 关键结果
CO2RR: FE 70.8%, j=53.8 mA/cm2 at -1.8V, 24h durability. Sensing: myricetin LOD 0.002 mM (0.01-50mM range); Cd(II) LOD 0.05 mg/L (0.1-20mg/L range). Performance tables compared against metal and doped-carbon catalysts.
面板 5： 机理
4-step CO2→formate pathway. Activity from: (1) microchannel mass transport, (2) hierarchical pores increasing triple-phase sites, (3) defect carbon (ID/IG=1.12) providing active sites without heteroatom doping.
面板 6： 创新点
- First wood bifunctional discovery. 2) Challenges dogma that pure carbon is CO2RR-inactive. 3) Natural architecture → no synthetic complexity. 4) One material, two functions.
面板 7： 局限性
Wood species not specified; FE (70.8%) not highest; no in-situ mechanistic evidence; carbonization conditions undisclosed; limited interference testing.
面板 8： 可迁移知识
Natural biostructures → electrochemical applications; defect carbon ≠ inert; hierarchical pore design for gas-liquid-solid reactions; dual-function electrode concept.
面板 9-10： 术语表与后续问题
