摘要

在本研究中，我们通过热分解方法成功地将金纳米颗粒加载到木质碳基材料上，开发了一种新型的tmb衍生比色探针系统，并研究了复合材料的比色检测性能。结果表明，木源碳基复合材料（Au/C）对Hg2+的检测灵敏度高（Au/C复合材料对Hg2+的最低检出限为0.2 nM），抗干扰性强，特异性强。此外，在0 ~ 200 nM低浓度范围内，Au/C复合材料呈现良好的线性关系。

Preparation of wood-derived carbon-based composites for highly efficient detection of Hg2+

In this study, we develop a novel TMB-derived colorimetric probe system by successfully loading gold nanoparticles on wood-derived carbon-based materials by thermal decomposition method, and the colorimetric detection performance of the composites was studied. The results show that the wood-derived carbon-based composites (Au/C) with high sensitivity (the lowest detection limit of Au/C composites for Hg²⁺ was 0.2 nM), anti-interference and strong specificity in detecting Hg²⁺. In addition, the Au/C composite material presented a good linear relationship in the low concentration range of 0–200 nM.
