【摘要】 邻苯二酚（CC）是高毒性的酚类污染物，对其灵敏检测对于环境监测具有重要意义。本研究以石墨烯（GR）为模板制备了石墨炔/石墨烯（GDY/GR）异质材料，作为检测CC的高性能电化学传感材料。GR在GDY生长过程中具有外延模板的作用。电化学实验结果表明，GDY/GR修饰的玻碳电极（GCE）对CC表现出优异的电化学响应，线性范围为1～900μmol/L，检出限低至0.11μmol/L。同时，GDY/GR/GCE还具有良好的抗干扰能力、稳定性和重复性。将GDY/GR/GCE用于实际水样中CC的检测，检测结果与高效液相色谱法测定结果一致，表明本方法在环境监测方面具有良好的实际应用潜力。更多还原

【Abstract】 Catechol(CC) is a highly toxic phenolic pollutant, and its sensitive detection holds significant importance for environmental monitoring. Herein, graphene was used as a template to prepare graphdiyne/graphene(GDY/GR) heterogeneous materials, serving as high-performance electrochemical sensing materials for CC determination. GR played the role of an epitaxial template during the growth of GDY. The electrochemical experiment results demonstrated that the glassy carbon electrode(GCE) modified with GDY/GR showed excellent electrochemical response to CC, with a wide linear detection range(1–900μmol/L) and a low detection limit(0.11μmol/L). Meanwhile, GDY/GR/GCE also exhibited good anti-interference ability, stability and reproducibility. More importantly, the practicality of GDY/GR/GCE was evaluated and satisfactory results were obtained in actual water samples, which showed significant potential for practical applications in environmental monitoring.更多还原
